Description of the Invention: [Technical Field of the Invention] The present invention relates to an apparatus and method for generating a fill pilot signal for hard delivery for a mobile communication, and in particular to allow a beacon (BeaC) 〇n) The device is capable of supporting a hard delivery device and method in a synchronous code division multiple access (CDMA) wireless communication network to use a base station (BS) classification pseudo-noise (pseud〇n〇ise, The pN) synchronizing signal to generate a dummy pilot signal, the base station classification pseudo-noise synchronization signal is taken from one of the base station CDMA radio frequencies (RF). [Prior Art] Typically, base stations (BSs) provide users with many communication services according to a ceU_based scheme, and move to another network from one grid (for example, a base station area) one ms. In the case of a cell (for example, another base station area), it is necessary to prevent a CAU drop between a mobile station (MS) and one of any base stations. By this method 'when M S moves from one base station area to another base station area, if a call signal is continuously maintained between the MS and the base station, this operation is called "submission". Usually, the delivery operation of a mobile communication system is classified into a hard delivery operation and a soft delivery operation. The soft delivery operation indicates a specific delivery mode, wherein when an MS is delivered from a first base station to a second base station, the second base station (eg, a neighboring base station) is assigned with the first base The station (eg, an existing Bs) has the same frequency assignment (FA) signal to the 1292674 MS. The hard delivery operation indicates a specific delivery mode, wherein the second base station (eg, a neighboring base) is delivered from a first base station to a second base station in synchronization with maintaining a call connection state The station assigns a different frequency assignment (FA) signal to the MS than the first base station (e.g., an existing BS). In this case, when the MS is hard-submitted between the first and second base stations having different FA signals, a beacon device is adjusted to prevent the occurrence of a call drop. Figure 1 is a conceptual diagram illustrating the operation of hard delivery between base stations.

參照第1圖，如果現在在一第一基地台” A ’’之一區域 利用一 FA2信號建立一呼叫連結狀態之該M S被遞交至一 第二站台” Bf•之一區域，在該第二站台"Β”不包括該FA2信 號的狀況下，該MS不能決定是否其位置存在於該第二站 台”Βπ之區域。為何該MS不能決定上述的狀態的原因是該 MS只具有能夠處理一頻率的無線電頻率硬體（H/W)模 組。因此，該M S持續進入該第二基地台π B ’’之區域，直到 該第一基地台ΠΑ”的FA2信號被切斷為止，因此無法建立 在該MS和該第二基地台ΠΒ”間的呼叫信號。 然而，如果該第二基地台’’ Β π把F A 2信號的填充領航 信號傳給MS，則該MS能確認到MS持續進入該第二基地 台n B "區域的目前狀態。因此，如果從第二基地台’’ Β n產生 的FA2填充領航信號的能量到達足夠強度，則該MS被硬 遞交至該第二基地台’’Βπ，以使該呼叫信號能夠維持於該第 一基地台” A ’’和該第二基地台π Β π之間。當該第二基地台” Β ·' 1292674 產生該FA2填充領航信號時，該FA2填充領航信號必 有等於一個基地台分類短PN碼者的預定時間偏移 (timeoffset)，用於該第二基地台ΠΒ·’的FA1領航通遒< 上述硬遞交操作係通常執行於一業預定的邊界 中，由每一基地台使用之FA信號數被改變為另—數 例如，一城内邊界或戶外/建築物内邊界、等等。如果 地台之FA信號數在城内區域及城外區城間之一邊界 被改變為另一數值，一信標裝置係安裝於一位於該域 域的一基地台，以允許安裝於一位於該城内區域的_ 台的FA信號數相等於位於城外區域之基地台者，以 在複數基地台網格間的遞交能夠輕易地執行。 二種規劃，即，下面的第一和第二規劃，可調整 用於上述的信標裝置。 第一規劃控制基地台"Β”以對基地台·，Β”產生的 RF信號執行耦合，因此該FA1 RF信號的一頻率被改 FA2信號者，並且最後如第1圖所示般傳送該FA2信 在使用第一規劃的情況下，藉由FA2信號傳送所有導 加最終放大器中的負載之通道信號（例如，_領航通 號、一同步通道信號、一傳呼通道信號和一交通通 號）。同樣地，一不預期之時間延遲在無線電頻率路徑 生，因此，F A 1領航信號的一短P N石馬時間偏移設定 能等於FA2領航信號者。 在第二規劃情況下，如果基地台” B"將充當基地台 信號的均勻時脈（CLK)信號提供給該信標裝置，旅且 須具 設定 ，其 值， 一基 區域 外區 基地 使在 以適 FA1 變為 號。 致增 道信 道信 中發 不玎 同步 —使 1292674 用者進入一短PN碼，該信標裝置控制這個短pn碼以進入 一時間偏移設定狀態，因此它產生一填充領航信號。然而， 第二規劃的缺點是該基地台必須為該信標裝置提供均勻的 CLK k號和一^參考時脈信號。Referring to FIG. 1, if one of the first base stations "A" is now using a FA2 signal to establish a call connection state, the MS is delivered to a second station "Bf" area, in the second In the case where the station "Β does not include the FA2 signal, the MS cannot determine whether its location exists in the area of the second station "Βπ". The reason why the MS cannot determine the above state is that the MS has only a radio frequency hardware (H/W) module capable of processing a frequency. Therefore, the MS continues to enter the area of the second base station π B '' until the FA2 signal of the first base station is cut off, so that it cannot be established between the MS and the second base station. Call signal. However, if the second base station '' Β π transmits the fill pilot signal of the F A 2 signal to the MS, the MS can confirm that the MS continues to enter the current state of the second base station n B " region. Therefore, if the energy of the FA2 fill pilot signal generated from the second base station '' Β n reaches sufficient strength, the MS is hard delivered to the second base station ''Βπ) so that the call signal can be maintained at the first A base station "A" and the second base station π Β π. When the second base station "Β · ' 1292674 generates the FA2 fill pilot signal, the FA2 fill pilot signal must be equal to a base station classification The predetermined time offset of the short PN code is used for the FA1 pilot of the second base station. The above hard delivery operation is usually performed in a predetermined boundary of each industry. The number of FA signals used is changed to another number, for example, an inner boundary or an outdoor/building boundary, and the like. If the number of FA signals on the ground is changed to another value at one of the boundaries between the city area and the city outside the city, a beacon device is installed in a base station located in the domain to allow installation in a city. The number of FA signals in the zone is equal to that of the base station located outside the city, so that the delivery between the complex base station grids can be easily performed. The two plans, i.e., the first and second plans below, can be adjusted for use with the beacon device described above. The first plan control base station "Β" performs coupling on the RF signal generated by the base station, and thus the frequency of the FA1 RF signal is changed to the FA2 signal, and finally transmitted as shown in FIG. The FA2 signal transmits the channel signals of all the loads in the final amplifier (for example, _ navigator number, a sync channel signal, a paging channel signal, and a traffic signal) by the FA2 signal using the first plan. . Similarly, an unexpected time delay is generated in the radio frequency path, so that a short P N stone time offset setting of the F A 1 pilot signal can be equal to the FA2 pilot signal. In the case of the second plan, if the base station "B" provides a uniform clock (CLK) signal that acts as a base station signal to the beacon device, the brigade must have a setting, the value of which is The appropriate FA1 becomes the number. The synchronization channel signal is not synchronized - so that the 1292674 user enters a short PN code, the beacon device controls the short pn code to enter a time offset setting state, so it generates a The pilot signal is filled. However, a disadvantage of the second plan is that the base station must provide a uniform CLK k number and a reference clock signal for the beacon device.
當藉由執行FA1信號的耦合使FA1信號轉變成FA2 信號時，用於上述二規劃之信標裝置控制一定向耦合器， 其連接至一基地台主要（BTS 一 MAIN)天線電纜，以執行一無 線電頻率信號耦合。該耦合的無線電頻率信號被傳送至_ RF跳頻單元，因此它的頻率被改變成另一頻率。在接連通 過高功率放大器（ΗΡΑ)和一個雙工過濾器之後，該轉變的 無線電頻率信號被傳送至一分集天線（ANT —DIV)。When the FA1 signal is converted to the FA2 signal by performing the coupling of the FA1 signal, the beacon device for the above two plans controls the indirect coupler, which is connected to a base station main (BTS-MAIN) antenna cable to perform a Radio frequency signal coupling. The coupled radio frequency signal is transmitted to the _RF frequency hopping unit, so its frequency is changed to another frequency. After the high power amplifier (ΗΡΑ) and a duplex filter are connected, the converted radio frequency signal is transmitted to a diversity antenna (ANT-DIV).
當從基地台得到Ε V E N — C L Κ信號時，如果信標裝置產 生填充領航信號，則它藉由 EVEN —CLK 槔口接收 EVEN一CLK信號和藉由參考時脈槔口接收參考時脈信號， 因此它把這個接收的EVEN — CLK信號用作一 PN產生單元 的BS短PN同步信號，並且把這個接收的參考時脈信號用 作一信標系統參考時脈信號。根據以EVEN —CLK信號為& 礎的使用者的ΡΝ建立資料，該ΡΝ產生單元產生具有—適 當時間偏移設定的領航信號。藉由RF跳頻單元，使餘r領 航信號轉變成一個RF頻率；被應用至一 ΗΡΑ和一雔τ 笑工過 濾器；和最後傳給一個分集天線（ANT_DIV)埠口。When the VEN VEN — CL Κ signal is obtained from the base station, if the beacon device generates the fill pilot signal, it receives the EVEN-CLK signal through the EVEN — CLK port and receives the reference clock signal through the reference clock port. Therefore, it uses this received EVEN_CLK signal as the BS short PN sync signal of a PN generating unit, and uses this received reference clock signal as a beacon system reference clock signal. The data is generated based on the user's data of the EVEN_CLK signal and the pilot generating unit generates a pilot signal having an appropriate time offset setting. The RF frequency hopping unit converts the residual r pilot signal into an RF frequency; it is applied to a ΗΡΑ and a 雔 笑 笑 filter; and finally to a diversity antenna (ANT_DIV) 埠.
在使該RF信號轉變成使用上述的信標裴置的 A 號的情況下，信標裝置有一優點，在於它有一簡化的架構^ 然而，上述的信標裝置有缺點，在於把除了領航诵、皆a 8 1292674 以外的同步通道信號、傳呼通道信號、和交通通道信號作 為負載應用於最後的輸出端放大器’因此如果它要傳送所 欲的信號，必須以高於只能傳送領航通道信號的另一放大 器5db的一預定的輸出水準。同樣地’上述^標裝置具有 另一缺點，在於它具有一不正確的短PN時間偏移設定， 其起因於RF路徑的時間延遲。同時’在自一外部接收傳 統時脈信號（EVEN_CLK)時產生一領航信號的情況下，該 信標裝置具有一缺點，在於基地台必須提供一短的PN碼 . * ,. 的EVEN_CLK信號和參考時脈信號。然而，信標裝置具有 一優點，在於它具有一相對簡化的架構。 在此期間，在韓國專利申請號20-2000-0020362中插 述另一信標裝置，標題為「能夠執行用硬遞交的改進信標 裝置」，其併入本文以供參照。上述韓國專利申請號 20-2000-0020362的信標裝置有一優點，在於它能夠藉由 調整一領航搜尋器為一符合的過濾器，以執行短PN碼之 快速同步化取得；及亦具有另一優點，在於因為當產生填 充領航信時’不會自一外部接收一同步時脈信號（例如，一 EVEN —CLK信號），所以可以輕易地與基地台互動。然而， 如果以符合的過濾器裝配領航搜尋器，在韓國專利申請號 20-2000-0 02 0 3 62中上述信標裝置需要大量閘道，雖然上 述信標裝置能夠只使用該領航搜尋器獲得一初始短pN 碼，但是無法彌補由一内部振盪器的頻率轉變產生的一短 PN碼的漂移之方法。此外，無法使輪出填充領航信號具有 適於基地台的頻率穩定性（^ ±0·05现所）。此外，上述信標裝置 1292674 使用用以延遲自領航I和Q產生器所產生的延遲J和Q信 號達一預定時間之一延遲，因它需要一額外的先進先出 (FIFO)記憶體。 【發明内容】In the case where the RF signal is converted to the A number using the above-described beacon device, the beacon device has an advantage in that it has a simplified architecture. However, the above-described beacon device has a disadvantage in that, besides piloting, Synchronous channel signals, paging channel signals, and traffic channel signals other than a 1 1292674 are applied as loads to the final output amplifier'. Therefore, if it wants to transmit the desired signal, it must be higher than the signal that can only transmit the pilot channel. A predetermined output level of an amplifier 5db. Similarly, the above-mentioned device has another disadvantage in that it has an incorrect short PN time offset setting due to the time delay of the RF path. At the same time, in the case of generating a pilot signal when receiving a conventional clock signal (EVEN_CLK) from outside, the beacon device has a disadvantage in that the base station must provide a short PN code. *,. EVEN_CLK signal and reference Clock signal. However, the beacon device has an advantage in that it has a relatively simplified architecture. In the meantime, another beacon apparatus is inserted in the Korean Patent Application No. 20-2000-0020362, entitled "Improved beacon apparatus for performing hard delivery", which is incorporated herein by reference. The beacon apparatus of the above-mentioned Korean Patent Application No. 20-2000-0020362 has an advantage in that it can perform fast synchronization of a short PN code by adjusting a pilot searcher as a matching filter; and also has another The advantage is that because a sync clock signal (eg, an EVEN — CLK signal) is not received from the outside when a fill pilot message is generated, it can be easily interacted with the base station. However, if the pilot searcher is assembled with a matching filter, the above beacon device requires a large number of gateways in Korean Patent Application No. 20-2000-0 02 0 3 62, although the above beacon device can be obtained using only the pilot search engine. An initial short pN code, but cannot compensate for the drift of a short PN code resulting from the frequency transition of an internal oscillator. In addition, it is not possible to make the wheel-filled pilot signal have a frequency stability suitable for the base station (^±0·05 is now). In addition, the beacon device 1292674 uses a delay J and Q signals generated by the delay pilots from the I and Q generators for a predetermined time delay because it requires an additional first in first out (FIFO) memory.

The function of the above-described internal components of the beacon device 500 is well known in the art, and is therefore well described herein, and thus its detailed description is omitted herein for convenience of description. The beacon device 500 receives the CDMA RF signal from the base station 210. In this case, the CDMA RF signal includes: a pilot channel signal, a synchronization channel signal, a paging channel signal, and a traffic channel signal, and the like. The CDMA RF signal received in the beaconing device 500 is transmitted to the binary separator 506 by the first BPF 504, and is distributed to the NMS terminal unit 502 and the first RF amplifier 508 of the NMS.
在第一 RF放大器508接收的CDMA RF信號508被放 大並傳遞至第二BPF 5 1 0以移除影像。第一混合器5 1 2使 從第二BPF 510產生的放大的CDMA RF信號與第一合成 器5 1 4的一輸出信號混合。The CDMA RF signal 508 received at the first RF amplifier 508 is amplified and passed to the second BPF 510 to remove the image. The first mixer 5 1 2 mixes the amplified CDMA RF signal generated from the second BPF 510 with an output signal of the first synthesizer 51.

Only one intermediate frequency (IF) signal is present at the output signal of the first LPF 516. In other words, the CDMA RF signal is converted to an IF frequency. The output signal of the first LPF 516 is amplified by the second RF amplifier 518, and the amplified signal passes through the surface acoustic wave filter 520. The surface acoustic wave filter 520 deletes the complex adjacent CDMA RF signals generated from the base station 210 and receives only a single CDMA RF signal.

The CDMA signal generated from the second lpf 530 is applied to the a/D converter 532. The A/D converter 532 converts the CDMA signal into digital data and performs sampling of the digital data at a rate at least eight times that of 1.22 888 Mbps. The digital CDMA signal converted by the a/d converter 532 into digital data is transmitted to the baseband processor 534. The baseband processor 534 receives a system clock signal from the system clock pll unit 538 and receives the output output tissue data from a user. The baseband processor 534 controls the first variable attenuator 524 to perform a receive gain control operation, and controls the control circuit 563 for generating a reference frequency of the beacon device 50A to reduce the base A frequency error associated with the station 2 1 〇. The baseband processor 543 performs a transmit power control operation and generates a fill pilot I/Q signal to allow the beacon device 500 to generate a fill pilot signal having the same short PN code as the received pilot signal. . The packed pilot kq signal generated from the baseband processor 534 is transmitted to the D/A converter 540 and then converted to an analog j/q signal. The analog I/Q signal generated from the D/A converter 540 passes through the third LPF 542 to remove the image signal. The pilot I/Q signal generated from the third LPF 542 is applied to the quadrature phase modulator 544 to convert it to an if signal. 17 1292674 The output signal of the quadrature phase modulator 544 is transmitted to the third BPF 548 to remove image signals other than a signal contained in a predetermined signal pass band. The output signal of the third BPF 548 is transmitted to the fourth RF amplifier 550' to amplify it, and the amplified signal is applied to the second variable attenuator 552. In this case, the second variable attenuator is adapted to adjust an output level of a fill pilot signal. The output signal of the second variable attenuator 5 5 2 is applied to the second mixer 555 to convert it into an RF signal. The output signal of the second mixer 556 is transmitted to the fourth bpf 558 to remove the image signal 'and the resulting signal without the image signal is applied to the fifth RF amplifier 560' to amplify it by the fifth rf amplifier 560. . The output signal of the fifth RF amplifier 560 is applied to ΗΡΑ 562 to be amplified with a large amount of power. If ΗΡΑ 562 amplifies the output signal of fifth RF amplifier 560 with a large amount of power, in addition to a predetermined frequency band signal, the Cavity BPF 564 removes the image signal and the glitch to generate a fill pilot signal. Figure 6 is a block diagram showing the internal architecture of a baseband processor in accordance with the present invention. Referring to FIG. 6, the baseband processor 534 includes a receive level controller 602, a transmit gain controller 604, a correlator 606, a phase deformation controller 608, a correlation energy value calculator, and a pN碣 clock control. The 610, a short PN code and trigger pulse generator 612, and a pilot signal generator 614, and the like. The receive level controller 602 checks 18 1292674 of a received digital I/Q signal to receive a CDMA RF signal with a predetermined power water for a predetermined period of time and control a receive gain. Yida, 曰S controller 6〇4 control According to the user to establish a capital transmission gain. Similarly, a receiving level of a receiving level controller 6〇2 is used; and a correlation energy value received from the correlation energy value calculator and the pN code clock controller 61〇, the transmission gain controller 6〇 4 Measure a pilot level of a received CDMA signal, and use the collar 2 level of the read measurement to control the transmit gain of an output fill pilot signal.
由於基地台210和信標裝置5〇〇間的一相位差，相位 變形不可避免地發生在接收的領航信號中。相位變形控制 器608比較相關器606的一輸出i/q相關積分值與一先前 的相關積分值，決定順時針方向旋轉或者逆川員時針方向旋 轉，和控制一參考振盪器的一電壓，以使接收的領航信號 的相位能夠無旋轉地位於一預定的位置。根據上述控制過 程，從基地台210接收的一 CDMA中心頻率變得等於信標 裝置500的一接收選擇中心頻率。Due to a phase difference between the base station 210 and the beacon device 5, phase distortion inevitably occurs in the received pilot signal. The phase deformation controller 608 compares an output i/q correlation integral value of the correlator 606 with a previous correlation integral value, determines a clockwise rotation or counterclockwise clockwise rotation, and controls a voltage of a reference oscillator to enable The phase of the received pilot signal can be located at a predetermined position without rotation. According to the above control process, a CDMA center frequency received from the base station 210 becomes equal to a reception selection center frequency of the beacon device 500.
相關器606包括乘法器和積分器。乘法器把一產生的 I/Q短PN碼乘以一接收的數位CDMA I/Q信號。從乘法器 產生的一數位值被應用於一積分器，並且該積分器積分一 預定時期内產生的數位值。對每個I/Q信號獨立執行乘法 和積分運算，以使獨立I/Q完整值從相關器606產生。 使用從相關器606產生的I/Q積分值，相關性能量值 計算器和PN瑪時脈控制器61 0計算一相關性能量值，使 用計算的相關性能量值決定與自己的短PN碼（即，一自體 19 1292674 產生的短PN碼）關聯的一相關位置，和控制一 pN碼時脈。 短PN瑪和觸發的脈衝產生器612產生欲由一接收器 使用的一 I/Q短PN碼，和產生一短PN碼的觸發脈衝信號 以產生領航信號。在這種情況下，I/Q翅PN碼產生器產生 對CDMA規劃合適的一 UQ短1^碼。用以產生一領航信 號短PN碼的觸發脈衝信號在短PN碼的每週期產生觸發脈 衝信號（即 ’ 1 /1.2288 McPs*215 « 26,67ms)。觸發脈衝產Correlator 606 includes a multiplier and an integrator. The multiplier multiplies a generated I/Q short PN code by a received digital CDMA I/Q signal. A digit value generated from the multiplier is applied to an integrator, and the integrator is integrated into a digit value generated within a predetermined period of time. Multiplication and integration operations are performed independently for each I/Q signal to cause independent I/Q complete values to be generated from correlator 606. Using the I/Q integral value generated from the correlator 606, the correlation energy value calculator and the PN-ma-clock controller 61 0 calculate a correlation energy value, and use the calculated correlation energy value to determine the short PN code with itself ( That is, a short PN code generated by the self 19 19292674 correlates a related position, and controls a pN code clock. The short PN and triggered pulse generator 612 generates an I/Q short PN code to be used by a receiver, and a trigger pulse signal for generating a short PN code to generate a pilot signal. In this case, the I/Q-fin PN code generator generates a UQ short 1^ code suitable for CDMA planning. The trigger pulse signal for generating a pilot PN short PN code generates a trigger pulse signal (i.e., ' 1 /1.2288 McPs* 215 « 26, 67 ms) per cycle of the short PN code. Trigger pulse production

When the pilot signal is generated, Navigator # says that the ancestor 614 produces a "signal that satisfies the IS-95 standard." The period of the short code is set to 26.67 ms', so the i/q letters outputting the pilot number each have a period of 2 6 · 6 7 m s. In order to utilize the above periodicity, the pilot k generator 614 includes a data memory device capable of storing a period of time of 14.67 ms of I/Q data. Therefore, when transmitting the pilot signal, the pilot signal generator 614 receives a trigger pulse from the short PN code and the trigger pulse generator 612, and adjusts the memory address at intervals of a predetermined time of 2 6 · 6 7 m s. A method for synchronizing a padding pilot signal of a beacon device 500 with a base station 210 when receiving a CDMA RF signal from the base station 210, the method being divided into first to third sub-steps. 20 I292674 The first sub-step relates the CDMA RF signal received from the base station to the ~self-generated short PN code' and confirms the start of one of the short PNs of the base station CDMA signal (i.e., one of the starting points of PN#0). The second sub-step utilizes the periodicity of the short PN ridge to delay a generation time of a trigger pulse to produce a transmit pilot signal such that a system time delay and a transmission/propagation delay can be compensated. The third sub-step periodically checks the CDMA RF signal received from the base station and compensates for a generation time for generating a trigger pulse for transmitting the pilot signal.

Indeed, if the program does not execute, a d d z e r 〇 ” program, the PN sequence has a predetermined period of "32767". Therefore, you must add the value of "zero,, to the pN sequence from 丨J聢. 14, the value of zero " appears continuously in the last sequence of I and from the nickname. In this case, the value of ''zero,' is added to the last sequence of I and Q letters, 4 to produce 32678 chips. If 14" I5 is generated when the receiver I/Q PN sequence is generated, 21 1292674 adds another "0" value to the 14" 〇" signal, and then at 1/〇 short 1^ the beginning of the sequence (ie, short ΡΝ #0开始), generates a trigger pulse of the receiver pN sequence. Fig. 8 is a timing diagram showing a method of compensating for a PN deviation between an input CDMA signal and an output pilot signal. The beacon device 5 causes an input CDMA signal having a predetermined time offset setting to be associated with a short pN code generated automatically in an AFC (Automatic Frequency Control) OFF state, and a result of the execution result signal Rotate (Slew) so that it looks up the ΡΝ#0 position of the CDMA signal.

In this case, the time delay, j" is a time delay from an RF input time to an input time of the baseband processor 534, and a processing time delay of the baseband processor 534.
第二子步驟係利用一短pN碼週期性，以延遲產生一 傳送領航信號的一觸發脈衝的產生時間，以補償系統時間 延遲和傳送/傳播延遲，該第二子步驟將在下文中詳述。 如果L “裝置查尋基地台21〇的pN#〇起點，應該傳 送一領航信號，以補償信標裝置500的時間延€。有許多 種時間延遲70# ’例如，—接收器的一時間延遲、一基頻 處理之一延遲、和一僂i关51从 . 寻廷益的一時間延遲。信標裝置使用 領航信號的週期性，補償上述時間延遲。 上述時間延遲補償被應 器的領航信號 用於一觸發脈衝，以產·生傳送 為了暫時安排在一 RF輸入埠口接收的 22 1292674 ㈣’和領航信號的輪出結果，以預定的時間延遲 11延遲該傳送領航信號，q生延遲的領航信號。The second sub-step utilizes a short pN code periodicity to delay the generation of a trigger pulse for transmitting the pilot signal to compensate for system time delay and transmission/propagation delay, which will be detailed below. If the L device looks for the pN#〇 starting point of the base station 21〇, a pilot signal should be transmitted to compensate for the time delay of the beacon device 500. There are many kinds of time delays 70# 'for example, a time delay of the receiver, A delay of one of the fundamental frequency processing, and a delay of one 偻i off 51. The beacon device uses the periodicity of the pilot signal to compensate for the above time delay. The above time delay compensation is used for the pilot signal of the receiver. In a trigger pulse, in order to temporarily arrange the 22 1292674 (four)' and the pilot signal's round-out result received at an RF input port, the transmission pilot signal is delayed by a predetermined time delay 11, and the delay of the transmission is delayed. signal.
第三子步驟定期地檢查從基地台21〇择收的_A k號，和補償用以產生傳送領航信號的觸發脈衝的一產 生時間，該第三子步驟將在下文中詳述。The third sub-step periodically checks the _A k number selected from the base station 21 and compensates for a generation time of the trigger pulse used to generate the pilot signal, which will be detailed below.
雖然在信標裝置500的輸入CDMA信號和信標裝置 5〇〇的輸出領航信號之間的延遲被補償了，值是它可能轉 換成另-時間延遲，因為在信標裝置5〇〇的—系統時脈信 號和基地台210的一系統時脈信號之間的一穩定性差異。 因此，使一預定的期間間隔接收的輸入Cdma信號相 關於信標裝置500的一短PN碼，計算出一特定相關性能 ΐ值，以該特定相關性能量值為基礎，能夠持續補償上述 時間延遲。當補償上上述時間延遲時，為了減少時間波紋Although the delay between the input CDMA signal of the beacon device 500 and the output pilot signal of the beacon device 5 is compensated, the value is that it may be converted to another time delay because of the system at the beacon device 5 A stability difference between the clock signal and a system clock signal of the base station 210. Therefore, the input Cdma signal received at a predetermined period interval is correlated with a short PN code of the beacon device 500, and a specific correlation performance threshold is calculated, and the time delay can be continuously compensated based on the specific correlation energy value. . When compensating for the above time delay, in order to reduce the time ripple
(ripples)，在a/D轉換期間信標裝置5〇〇至少執行8過度 取樣（over samp ling)操作，和決定用以產生傳送領航信號的 觸發脈衝之產生時間的一控制解析度為”丨/24 chip"。在這 種情況下，執行AFC操作以部署信標裝置50〇的系統時脈 穩定性。僅供參考，由Qualcomm公司製造的終端設備已 被設計為能夠在A/D轉換期間執行4個過度取樣操作。 第9圖是說明用於控制基頻處理器534以產生填充領 航信號之一方法的概念性圖示。 參考第9圖，所有領航資料單元都被設定成” 〇"而 Walsh資料也被設定成”〇”，因此由ι ·2288 Mbps的Walsh 資料調變每一領航資料。在這種情況下，把該輸出信號分 23 1292674 成二部分，並且根據從一外部元件接收的一觸發脈衝，藉 由從一 Ι/Q短PN瑪產生器產生的一 pN碼調變該二部分。 在這種情況下，I/Q知 PN碼的序列期間具有2 15的一預定 的長度（即，32768 chips)。(ripples), during the a/D conversion, the beacon device 5 performs at least 8 over sampling operations, and determines a control resolution for generating a trigger pulse for transmitting the pilot signal as "丨" /24 chip" In this case, the AFC operation is performed to deploy the system clock stability of the beacon device 50. For reference only, the terminal device manufactured by Qualcomm has been designed to be able to be used during A/D conversion. Performing 4 oversampling operations. Figure 9 is a conceptual illustration of a method for controlling the baseband processor 534 to generate a fill pilot signal. Referring to Figure 9, all pilot data units are set to "〇" And the Walsh data is also set to "〇", so each pilot data is modulated by the ι · 2288 Mbps Walsh data. In this case, the output signal is divided into two parts, and according to a trigger pulse received from an external component, the two are modulated by a pN code generated from a Ι/Q short PN generator. section. In this case, the sequence of I/Q known PN codes has a predetermined length of 2 15 (i.e., 32768 chips).
由定標器（scaler)控制pn碼所調變的上述資料的增 益’而後應用至Finite Impulse Response(FiR)過濾器。除 了適於IS ·95標準的基頻信號以外，FIR過濾器移除諧波 信號。FIR過濾器執行接收信號的4過*** (over-interpolation)的操作，和輸出結果信號。 因此，由於PN碼週期性，傳送數位I/Q領航信號具 有週期性’以使信標裝置500儲存一單一期間的uq領航 信號（即 ’ l/1.2288McPs * 32768 s 26.67ms)在一資料記 憶體’和定期地重複I/Q領航信號的上述儲存操作，從而 產生結果I/Q領航信號。 第10圖係說明用以產生I/Q領航信號之一資料記憶 的一内部架構的一方塊圖。The gain of the above data modulated by the pn code is controlled by a scaler and then applied to a Finite Impulse Response (FiR) filter. In addition to the fundamental frequency signal suitable for the IS 95 standard, the FIR filter removes the harmonic signal. The FIR filter performs an over-interpolation operation of the received signal, and outputs a resultant signal. Therefore, due to the periodicity of the PN code, the transmitted digital I/Q pilot signal has a periodicity 'to enable the beacon device 500 to store a single period of the uq pilot signal (ie 'l/1.2288 McPs * 32768 s 26.67 ms) in a data memory The body's and the above-described storage operations of the I/Q pilot signals are repeated periodically to produce a resulting I/Q pilot signal. Figure 10 is a block diagram showing an internal architecture for generating data memory for one of the I/Q pilot signals.

Stored in a single data file. In the time delay 2 of 〇.25”chip, the pilot data from the "0" address to the "131〇71" address is stored in the pilot data memory area' and In the time interval between "〇.25"chip, the Q-leading money from the "0" address to the "13 1071" address is stored in the Q pilot data memory area. 24 1292674 A method can be used to interact the output frequency of a base station with a beacon device output frequency to ensure the stability of the output frequency of the beacon device, as will be described in more detail below. Output Frequency Stability of Beacon Device 500 The standard is determined to be 0.05/?pm and less' and must guarantee the same frequency stability as the base station. In order to ensure the above frequency stability, it is necessary to consider one of the reference oscillators as the beacon device 500. Temperature stability, and to respond to stability over the past few years. In this case, if the beacon device 500 uses a high-stability oscillator (ie, an oscillator of 0cx0 level), it will increase it significantly. of In order to solve the above-mentioned production cost problem, the beacon device uses a voltage controlled oscillator (ie 'TCX0)' and uses the CDMA RF signal it receives to deploy an AFC function, so its function is close to the base station reference oscillator. In order to provide high frequency stability of the beaconing device 500, a reference oscillator voltage control operation is performed using a resolution of at least 10 bits. For example, a terminal device manufactured by Qualcomm has an 8-bit state. AFC resolution. A method that can be used to interact with the output level of a base station and the output level of a beacon device, as described in more detail below. An output level system for generating a conventional beacon device that fills a pilot signal Fixed by the user. If the base station increases or decreases the total output level, it also changes the service area of a base station to respond to the increase or decrease of the output level, so the output level of the beacon device must also be changed to another The standard. However, the disadvantage of the traditional beacon device is that although a base station pilot power has been replaced by another power, it However, the output level cannot be changed. For solving the above problem, 25 1292674, a method is needed for the output level of the base station to interact with the output level of the beacon device. The CDMA RF signal received at the RF port includes the pilot channel signal, Synchronous channel signal, paging channel signal, and multiple traffic channels. The power of the input CDMA RF signal is continuously changed by the number of communication users. Therefore, the power of the pilot channel signal can be confirmed by the CDMA RF signal, and the confidence flag can be generated. The pilot signal of the device performs a power control operation. When an automatic gain control (AGC) operation is performed, the beacon device 500 confirms a reception level of the CDMA RF signal. Similarly, since the correlation energy value changes linearly due to the number of traffic lanes, the correlator 606 included in the baseband processor 534 calculates a correlation energy value, and based on the calculated correlation energy value, receives the CDMA. As a whole power of the RF signal, 'calculate a power ratio of the pilot channel signal. Therefore, the beacon device controls an output level of the fill pilot signal such that the ratio between the power of the fill pilot signal to be generated and the received level of the CDMA RF signal confirmed by the AGC execution is equal to the calculated power ratio. If the base station 2 1 〇 completely increases or decreases the output level, the power of the pilot channel signal is also increased or decreased, and the beacon device 500 outputs its output level by detecting the power rate of change of the pilot channel signal. It will be apparent from the foregoing that, in accordance with the present invention, an apparatus and method for generating a fill pilot signal uses a sequence number searcher plan to obtain short PN code synchronization from a CDMA RF signal when the beacon device generates a fill pilot signal. Thus, the short PN code drift generated by the frequency conversion 26 1292674 of an internal oscillator can be compensated without requiring a large number of gates. Similarly, the output fill pilot signal has a frequency stability (<(O)O.OSppm) that is suitable for the base station, and is used to generate such a fill pilot signal when receiving a conventional EVEN-CLK and reference clock signal. In the conventional method, the above device does not additionally receive an EVEN-CLK signal and a reference clock signal, and a simplified architecture of a base station interface can be obtained. Although the preferred embodiment of the present invention has been disclosed for the purpose of illustration, it will be understood by those skilled in the art that various modifications, <RTI ID=0.0>> The scope and spirit of the scope of the patent application.
