Description of the invention (/) The present invention relates to a multiplex transmission system, and more particularly to an intelligent heterogeneous code multiplex transmission system. In order to increase the capacity of the optical fiber communication system, in the past, it has been operated by time division multiplexing (TDM). However, the time division multiple union is limited by the bandwidth of the optical fiber. In recent years, everyone has actively developed the wavelength division multiplexing method. Division Multiplexing · 'WDM), that is, using a multiplexer to multiplex the signals of each channel of different wavelengths into a single optical fiber, and the receiving end divides each channel with an optical demultiplexer. However, the traditional optical fiber code division multiplexing (CDMA) system technology has been extensively discussed recently. Modified digital codes (refer to the? 7 and? 3 modified digital codes shown in Figure 1) are used for decoding. Method, in Asynchronous Code Division Multiple Access (CDMA) > there can only be P group decoding capacity (P is the selected prime number). In Synchronous Code Division Multiple Access (S / CDMA), it has P2 group decoding capacity. The encoder / decoder used in the optical CDMA system is still insufficient in the application of the decoder of the optical fiber communication system. Synchronous code division multiplexing is the use of data to spread the digital spectrum. The synchronization of each chip enables the decoder to identify more high-quality digital codes. Take P7 Code as an example: when asynchronous, the decoder only Can identify 7 codes (p7 = 7); and when synchronizing, the decoder can recognize 49 codes (P72 = 49). If we transmit data at the speed of 10G / Sec, it is equivalent to being transformed into 490G by p7 Code / Sec's Chip Rate, how to do this in fiber 3 --- II I --- I Ix) y * ^ ----- --- I ---- — II < Please read the back Note: Please fill in this page again.)

The paper size applies the national standard (CNS) A4 specification (210 x 297). 4 444 5 2 5514twf.doc / 008_B7 ____ 5. Description of the invention (Up) Ultra-high-speed synchronization will be a very difficult task. {Please read the general matters on the back before filling this page.) In asynchronous multiplexing, 'because its optical decoder does not contain synchronization data, it can only distinguish p kinds of digitals of different quality, so it has p group decoding capacity. That is, only P users can use one transmission channel at the same time. In the above-mentioned synchronous multiplexing, because the optical decoder contains synchronous data, it can discriminate P2 different digitals. The P2 group decoding capacity, that is, a maximum of P2 users can use one transmission channel at the same time. Although the overall capacity is increased, it needs to be synchronized, the design is difficult, and the hardware complexity is high. Especially in the design of the decoder of the actual optical communication system, the synchronous work processing is more difficult. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. For example, under the traditional asynchronous system, the data to be transmitted is spread out using asynchronous digital, and transmitted to the decoder at the receiving end. (Decoder) uses the technology of the delay line to determine its threshold (Threshold). Whenever it exceeds the threshold, it means that the decoding is successful and the required data is retrieved. Please refer to Figure 2. Under the synchronization system, the decoder at the receiving end 10 uses the technology of the delay line 20 to determine its threshold ThreShold 30, and the sampling is synchronized with the transmitting end. Time (Sampling Time) 40. Only at a specific sampling time 40 can it be judged whether it exceeds the critical threshold. However, due to the frequency of data spreading, the number of Chips will increase significantly (Take the P7 Code as an example: 1-bit data will be spread to 49 Chips, as shown in Figure 3). The larger the digital quality is, the brighter it becomes. 4 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) V 4 444 5 2 A7 5514twf.doc / 008 β7 Printed by the Consumers ’Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs System 5. Description of the invention (now) It is obvious that, especially in high-speed communication, it will be difficult to synchronize the sampling time. This disadvantage is also the most challenged part of the synchronization system. Therefore, the present invention provides an intelligent heterogeneous code multiplex transmission system, which utilizes the characteristics of two different heterogeneous digital codes that do not interfere with each other, combines them and replaces the conventional non-synchronous code division multiplexing system. In the transmission system, additional users or other types of data are dynamically added to improve the shortcomings of the insufficient capacity of the high-quality digital system, thereby increasing the decoding capacity and achieving multi-purpose purposes. The invention provides a kind of synchronous parallel-quality digital, which uses a combination of dissimilar digitals to enhance the original asynchronous decoding capacity, and can be used in asynchronous systems, but has the decoding capacity of an approximately synchronous system, and has ultra-high capacity and High speed characteristics. The present invention provides a smart heterogeneous digital multiplexing transmission method, which is briefly described as follows: Under normal conditions, the heterogeneous digital multiplexing transmission system operates with the first quality digital system. The monitoring system selectively adds the second-quality digital system based on the combination of the first-quality digital system. When the monitoring system does not include the second-quality digital system, the heterogeneous digital multiplexing transmission operates with the first-quality digital system. When the second-quality digital system is added to the monitoring system, the heterogeneous digital multiplexing transmission operates with the first-quality digital system and the second-quality digital system. The present invention provides a smart heterogeneous digital multiplexer, which is briefly described as follows: An optical decoding array for capturing the first quality digital signal in an optical fiber, 5 (Please read the precautions on the back before filling this page). ), Language

Description of the invention (1) Increased system capacity, so it has become the mainstream of the next generation communication system. Optical fiber communication has been more deeply used in multimedia transmission in recent years. We found that in the CDMA environment, codes of different lengths can be conditionally compatible. At the receiving end, some specific codes can be identified, which is the difference of heterogeneous digital The design basis of the code multiplexing system and heterogeneous code multiplexer. The present invention will aim to form a heterogeneous digital system architecture in the CDMA environment with encodings of different lengths, which can solve the shortage of decoding capacity and increase the number of simultaneous users. In addition, the design of heterogeneous code multiplexers, system capacity, and possible range applications under this architecture have improved the shortcomings of traditional CDMA. In this multiplexing system, we have designed a new type of code-division multiplexing system and its optimized design method to increase the integration capacity. In the original Pl-quality digital system (first-quality digital system), place a Ps (second-quality digital system) of a heterogeneous digital system to coexist and transmit (where ps represents a different prime number respectively), and find compatible The "transmission conditions" enables two different kinds of data or different users to use the heterogeneous digital spread spectrum that will not interfere with each other, and can simultaneously transmit the purpose, and design the multiplexer hardware.

Description of the Invention (Bu) (Please read the notes on the back before filling this page) The P7 quality digital used is the Despreading Code of its decoder 74. At this time, the monitoring center (Monitor Center) 90 will monitor this CDMA system 80. When the P7 Code combination used can add some P3 Code quality digital, the Monitoring Center 90 will use the available P3 Code to optimize the algorithm (Optimal Design Algorithm) 100 is optimized and handed over to the Multiplexing Control Center 110, thus adding another Users: User'l, User'2 ...

Description of the invention ((\) algorithm calculation The multiplexing control center is added to the system to become? 7 and p3 are different in the digital multiplexing state 150. Because the multiplexing control center adds the P3 Code to the original single-quality digital system, even if the P7 Code and p3 Code systems are thrown away , Then the entire system will enter a heterogeneous digital multiplexing state, and other users can be added at this time. (5) Use the corresponding decoder to despread the spectrum 160. (6) Take the threshold to determine whether it is the signal 170 (7) When all the used digits are judged as the required signals, and other unused digits are not the signals, then this group is a successful combination 180, otherwise it is a failed combination 190. So After selecting the P7 Code, without affecting the original system (p7 Code System) transmission, insert the P3 Code at the most appropriate position to achieve the purpose of increasing capacity without causing mutual interference. Please refer to Figure 6 , P3 The dynamic insertion position of the code is the time slot insertion method. This method of adding heterogeneous codes is to dynamically control the position where each heterogeneous code is added. Therefore, in different situations, the positions where different heterogeneous numbers that are accommodated at the same time may not be fixed. Each time you add a heterogeneous code, it depends on the different heterogeneous digits that can coexist, that is, you don't adopt the way of vertical alignment, that is, the heterogeneous codes may partially overlap and partially stagger. Please refer to sections 7A, 7B and 7C Figure, which is shown as an optimized algorithm model. We observe the sum (Sum) composed of 7 selected codes, in order to improve the entire method of adding heterogeneous codes and effectively decode 13 paper standards that comply with Chinese national standards (CNS > A4 specification (210 X 297 mm) ---------- install --- I --- 丨 order i I ------ line, {Please read the precautions on the back first (Fill this page) M4452 5514tvvf.doc / 008 A7 B7 5. Description of the invention ((（) process, we found: (a) To be able to add the P3 Code to the single-quality digital system originally composed of the P7 Code, the P7 Code Must be included in the sum (Sum) of Code "0"; but on the other hand: the presence of Sum does not necessarily mean that P3 Code can be added, so as long as we look for the possibility of adding a heterogeneous code here, we can speed up the search, as shown in Figures 7A and 7B. (B) Figure 7C shows the optimization algorithm model. When P3 Code is added to the original system, if the relative position of the sum (Sum) corresponding to the relative position of P3 Code is 1, the relative position of Sum is 0 or greater than 2. When the relative position of the sum (Sum) corresponding to the relative position of P1 is 1, the P3 code cannot be added. This can shorten the decoding time and improve the overall performance. To make adding heterogeneous codes faster. Therefore, the use group in the entire optical fiber communication network originally used Pi (Pl is a prime number) as the spreading code for transmission, that is, when transmitting and receiving data, the corresponding Pl-quality number was used, and it was added After the multiplexer, the entire system is a heterogeneous code multiplexed transmission system as shown in Figure 8. PS can be added (PS is a prime number). In the illustration we assume that there are five users in the entire network, two of which are Each user (User2, User4) is equipped with a heterogeneous digital multiplexer (PL + PS), so these two users can use the multiplexer to transmit different data in addition to achieve the purpose of multimedia transmission.

With the transmitting end, it is determined whether the channel is already used. The sampling time is determined by CLK1, CLKbPjxTXsec); the previous signal needs to be amplified by the optical amplifier 352, because there are PJ decoders in the decoding array, the energy will be dispersed to the original 1/1 \ 2, and The delay line logic in each decoder 354 will disperse the energy to the original 1 / PL, so its magnification (G) is: G = PL2xPL. C0SR 360: Please refer to Figure 12, because currently there may be several users, the digital data transmitted is exactly 0, and it will not be spread by high-quality digital. At this time, the aforementioned optical decoding array will cause a misjudgment that there is no such. The user exists, so we designed the channel occupancy detector 360. According to the user solved by the previous optical decoding array 350, observe the Ns bit (received by the Ns bit shift register 352, and the Ns bit can be customized) ), Then determine the number of true 1 \ quality digital use in the channel, that is: As long as the user has any 1 quality digital spread spectrum in the Ns bit register 352, it will be found by the OR gate 364 detector On the contrary, if you use it (please read the precautions on the back before filling this page)-/ Λ V > ϋ n ί nnn a 5 ', _ nn line}.

Description of the invention (K) Those who do not have any 1s in the Ns bit will spread the spectrum. It may cause misjudgment. If the channel occupancy detector 360 considers that the data transmitted by each user is 0, the optical decoding array will not be able to correctly determine the existence of this user, which may cause the judgment of the subsequent multiplexing situation, so we design the channel Occupancy detector 360, we write the data obtained from the optical decoding array into the Ns bit register 362 ', and also use CLK1 as the control signal, shift right to the right-once, and reset (Reset) once every Ns bit, Restart the detection. To determine the error, it is possible that the data in each bit of the Ns bit is 0, which is a very small opportunity. The length of Ns is determined by the user. The larger the temporary register, the higher the cost, but the lower the possibility of misjudgment. In each CLK1 cycle (PL2xT sec), the signal sent by the ODA 350 is sent to the Ns bit register 352, and the OR gate 364 determines whether there is a signal, and in the CLK2 cycle (NsxPL2T sec), the Ns bit is temporarily stored. The register 352 is reset, and the channel signal occupied by the switch 366 is sent out when resetting. SOSR 370: Please refer to Figure 13, through the aforementioned channel occupancy detector 360, to detect what is actually used in the current channel? The high-quality digital data is then occupied by the time slot occupancy detector 370, and the corresponding sum Sum is reconstructed with each Ns bit, and written into a register. The Pi2 bit shift register 372 is initialized by using the data in the P7 ROM Table (read-only memory that stores P7 quality digital data). It is controlled by CLK3 = NsxT (SeC), and is shifted by 1 bit at a time. The first bit, and after the user is detected as described above, after sampling by CLK4 = NsxT / Pl2, a two-bit counter 374 reconstructs the complete sum (Sum) 'and writes into a PL2x2 bit (please Please read the notes on the back before filling this page) This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 ^ 297 mm) 444452 A7 .. 5514twf.doc / 008 _ B7 V. Description of the invention (p) Temporary Register 376, the four possible situations of the register, every two registers are a group, if this Chip is 0, the register is 0; if this Chip is 1, the register is 0; If the Chip is 2, the register is 10; if the Chip is 3 (3, 4, 5, ...), the register is 11. This step is to determine whether 2 exists in the total Sinn. When 2 exists, it is impossible to add P3 prime digits. When 2 does not exist, multiplexing with different prime numbers can be performed. ODD 380: Please refer to Figure 14. Under normal communication conditions, when there are not many users, the multiplexer can automatically determine the usage in the channel (calculated by the adder 382) and dynamically add another heterogeneous code; and If the number of users increases suddenly, the overload determiner 380 will determine the number of users and the setting 値 N from the previous channel occupancy detector 360. To determine if it is currently busy, of which N. It can be set according to the user's needs. The larger the No, the smaller the channel restriction, and the more it can belong to multiplexing, but the smaller the ability to protect the sudden increase in usage. In order to maintain the normal operation of the main communication users, we have added an overload judger. When there are too many users, we will send a setting signal to refuse to enter the multiplexing state. The setting 値 N0 can be determined by the user. IPU 390: Please refer to Figure 15. We use a simple logic circuit design to implement the hardware of the aforementioned optimization algorithm. The heterogeneous code read from the P3 Table is compared with the sum (Sum) of the previous reconstruction, if desired. Each Chip in the added heterogeneous code is consistent with the sum (Sum). Fj indicates that the Ps heterogeneous code can be added, and a permission signal is sent at this time. (Please read the precautions on the back before filling in this page.)

Description of the invention (α) We use a simple logic circuit combination such as the circuit in Figure 15, which is controlled by CLK2 and reads the data of ps2 bit2 each time Compared with the heterogeneous numbers in the Ps Table, the comparison method is as described in the previous optimization algorithm.

ICU 400: Please refer to Figure I6, using the join processing unit 39 to share a clock (CLK5) with the join control unit 400 to achieve the synchronization effect 'and when the join processing unit 390 detects that a heterogeneous code can be added (permission Signal), by adding the control of the control unit 400, multimedia data is re-coupled into the optical fiber after corresponding laser and delay line logical coding, and the design of adding multimedia data (input signal) to the original system is completed. When the joining processing unit 400 finds that the ps code can be added, the same clock CLK5 = NsxT / Ps2 is used to achieve the synchronization effect. The multimedia data in the buffer is encoded by the corresponding encoder and recoupled into the optical fiber. The action of adding heterogeneous numbers is shown in Figure 16. DPCD 410: Please refer to Figure 17, the receiver must also have the same hetero-code multiplexer, because the receiver will receive both the P1 and ps-quality numbers in the fiber, but it will be determined by the optimization algorithm. The two inserted heterogeneous numbers are orthogonal to each other, so the two will not interfere with each other. That is to say, in the original decoder, only high-quality digital data can be decoded. We design the heterogeneous digital decoder as described below: After coupling the signals in the optical fiber, use the same method to determine the type and position of the added heterogeneous code.

The multiplexing state will end, and multimedia data transmission will be suspended until the channel resumes normal status again. Next, we will introduce the synchronous digital encoders and decoders. In optical fiber communication systems, Prime Digital is generally used as the spreading code. Therefore, in order to understand the working principle of encoding and decoding, we will first introduce the signal characteristics of Digital. : When we make asynchronous encoder, we pass the data through the delay line (Delay Line) to produce quality figures. For example, Data "1" becomes CO after Delay = 1, 3, 6 and 0 = 100 100 100 ; Pass the encoded digital quality through the delay line of the asynchronous decoder and observe whether it exceeds the critical threshold (Th = 3) of the P-3 Code to determine whether the decoding is successful, as shown in Figure 21. Synchronous code-like concepts. In order to simplify the discussion, the overall system will be designed with P7_Code and P3-Code as representatives in this manual. The design ideas will also be included in other unique code systems. 'It is encoded with a single kind of digital code (such as P7-Cope); and we combine two different kinds of digital codes (such as P7-Cod and P3-Co & ie) into a new spread spectrum code. Quasi Synchronous Prime Code), and then decode from it, as shown in Figure 22. Among them, each bit data is spread into 58 chips (P7 + P3 = 49 + 9 = 58) by using a class-like synchronization code, as shown in FIG. 23. Coding system design: Please refer to Figure 24. 'First we explain how to actually use two different quality digital systems (P7-Code and P3-Code) to generate class-like synchronization codes, and set 24 paper standards to Chinese National Standard (CNS) A4 Specifications_ (· 21〇χＯ 公 楚) (Please read the precautions on the back before filling out this page) Pack 111— »1111111. 4 4 4 4 5 2 ^ 5I4twf.doc / 0Q8 A7 B7 Employees, Intellectual Property Bureau, Ministry of Economic Affairs Printed by Consumption Co., Ltd. 5. Description of the invention) The coding system is as follows: A. The data will be separately sent to the encoder used by the original asynchronous system, and the delay line technology (as described above) will be used to encode. The mature encoder technology in the synchronization system does not require an additional encoder. B. The biggest difference with encoders of asynchronous systems is that the data first passes through a delayer 430 (Delay) and then is sent to the P · 7 Ｃode encoder, and the delay time is determined by the chip length of the P-3 Code as 9L (P3 = 9) 'When combining different types of digital quality, the length of the delay must be determined separately. The outputs of the C_P7 and P3 encoders are then coupled together by a coupler 44 to form a new encoding technology, which is called a class of synchronous encoding. Finally, it is sent to the optical fiber transmission system for transmission, which completes the design of all synchronous encoding systems, as shown in Figure 24. Decoding system design: Please refer to Figure 25, and after completing the synchronization code encoding, we design a synchronization decoder, in order to correctly solve the transmitted data, capacity and approach the synchronization system: A. Assume that it constitutes synchronization The two different digits of the code will have critical thresholds at the positions of Y and X, and because they are composed of P_7 Code and P-3 Code, their critical thresholds are Th = 7 and Th = 3, respectively. B. After receiving the synchronization code, the receiver sends the data to the decoder used by the original asynchronous system, and uses the delay line technology (as described above) to decode it, and determines whether it exceeds the critical threshold.

Description of the Invention 〇4) The mature decoder technology in the synchronization system does not need to design another decoder. C. The biggest difference with decoders in asynchronous systems is that the data is first sent to a delayer (Delay) 1 after passing through the P-3 Decoder, and the delay time (Delay = YX) is critical by the P-7 Code 値 ( Th = 7) The difference between the position (Y) and the P-3 Code critical threshold (Th = 3) is determined by the difference.

The two outputs are then coupled by a coupler and sent to another critical threshold determiner, whose critical threshold is determined by the two prime digital systems that make up the same step code (Th = P3 + P7 = 3 + 7 = 10). E. Because the P-3 Decoder was delayed by the delayer (Delay = YX), the critical 値 of the P-7 Code and P-3 Code systems have been translated to the same position, so only the classes we have designed are synchronized. Code, its critical threshold will reach the highest threshold, and the other combinations of P-7 Code and P-3 Code fail to decode because the critical threshold is not translated to the same position. F · Finally, the received class-like synchronization code is converted into the originally sent data, and the entire design is completed, as shown in Figure 25. And we take quality digital 3 and quality digital 7 as examples, and use the programming language (Turbo C) simulation ’to verify that the new type of synchronous digital quality composed of Prime Code 3 and Prime Code 7 will not interfere with each other. 'Therefore, the advantage of the present invention is to propose a smart heterogeneous code multiplexing transmission system' which uses the characteristics of two different heterogeneous digital codes that do not interfere with each other, combining them and replacing the conventional asynchronous asynchronous code multiplexing system, And in the original fiber-optic transmission system, another user was dynamically added. 26 This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 public love) \ lp / Λ—y ------ 1 --- ---. .Installation ------- Order --I ------ line-- (Please read the precautions on the back before filling this page) Printed by the Intellectual Property Bureau Employee Consumer Cooperative of the Ministry of Economic Affairs 444452 A7 _5Sl4twf.doc / Q08 _____ jg7 5. Description of the Invention (〆) or other types of data, to improve the shortcomings of insufficient capacity of high-quality digital systems, and then to increase the decoding capacity to achieve the purpose of multitasking. Another advantage of the present invention is to propose a 1-tumor synchronous parallel digital, which uses a combination of heterogeneous digitals to improve the original asynchronous decoding capacity and can be used in asynchronous systems, but has a decoding capacity similar to that of a synchronous system. It also has the characteristics of ultra-high capacity and ultra-high speed.
