Description of the Invention (j) The present invention is a smart antenna system with a space filter group structure. It is a signal that can transmit or receive signals. Independent processing according to the difference of the beams' enables each beam to achieve the high efficiency of parallel processing, and achieves a significant reduction in hardware accuracy and software complexity, resulting in the effect of improving system capacity, distance and range and improving communication quality. According to the current Smart Antenna System (SAS), it can be divided into two categories: beam switching (SWITCHED BEAM) and adaptive zeroing (ADAPTIVE NULLING). The beam switching system is based on time sharing ( The TI ME SHARING method is used for spatial division, which causes multiple beams to sequentially transmit / receive. However, when the number of beams increases significantly, 'that is, the time allocated for each beam is insufficient, which limits the flexibility of the application'. Does not meet the requirements of high efficiency. And for the adaptive zero-tuning smart antenna system, it can automatically track the user ’s use situation, and according to the environment and user location, in a customized (CUSTOMIZED) manner, the antenna is dynamically adjusted. Axial field range 'achieves the dynamic zeroing (NULUNG) operation of interference, and exerts the best transmission / reception efficiency. If the typical field pattern of adaptive zeroing formed by setting eight antenna units is shown in Figure 7 (Excerpted from GiOM / Virginia Tech), and the shortcomings derived from the following are summarized as follows: 1. The antenna gain is shown as zero in the picture And doing some sacrifices 'the rate of change of the field pattern near zero is very large, the difference in angle is small, and the attenuation effect is greatly changed. Under the influence of the environment, it is extremely difficult for the user to accurately locate the position', so the effect of zeroing is limited. 2 _In order to achieve the aforementioned dynamic adjustment function, its hardware is linear and paper-based, which is applicable to the Chinese National Standard (CNS) Α4 threat (2 丨 0 > < 297) (please read the legal notice on the back before filling in (This page)-Install A7 B7 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs. 5. Description of the invention (V) The requirements for uniformity and accuracy are very strict, resulting in high costs. 3. Multi-user positioning and field-type zero adjustment The algorithm is quite complicated, the update rate of the antenna field type is high, and it requires a high calculation load. 4. Under the channel of the limited space filter, the allocation to multiple users is not good. 5 · The system can be controlled The number of beam zeros is less than the number of antenna elements. If there are a large number of users, the zero adjustment cannot match the number of users, leading to the disadvantage of uneven distribution. Θ. For wireless communication, the base station uses independent transmission and reception. Since the frequency difference between the uplink and downlink frequencies is large, there is almost no correlation between the optimal path for transmission and reception, which makes it difficult to estimate the field pattern of the transmitting antenna. In terms of the antenna system, that is, with a large number of users and an environment full of uncertainty, not only the software and hardware structure is too complicated and the load is too large, the effect is also limited. Therefore, no matter whether beam switching or adaptive tuning is used The zero antenna system cannot provide the advantages of efficiency and simplified structure at the same time, and it is obviously necessary to solve it. Therefore, the main object of the present invention is to provide a smart antenna system with a space filter group structure. The space filter subgroup constructed by the space filter and the array antenna composed of a plurality of antennas constitute the transmitting and receiving system of the present invention, and the amplitude of each antenna unit in the array antenna is performed through each space filter in the space filter group. The phase and phase are independently controlled to obtain a sufficiently low side wave level, and most beams can be parallel to the paper scale at the same time. * Magic with the public (please read the note and then fill in the back of this page) - installed ·

Description of the invention {f ~) ---) The output signal is then placed on the receiving bus (3 3), and then obtained by each digital beamformer (3 5) from the receiving bus ㈡㈧ The output of each antenna unit (32) is accumulated by the complex weight whichever ING) to form a specific space ferry wheel. (The signal of the complex form multiplied by the complex weight is the amplitude and phase of the signal.) Finally, Send it to the base station (10) for subsequent processing. In this way, the receiver of the antenna system is received. Under the configuration, the space waver group (3 j) is composed of a plurality of digital beamformers (3 5) connected to the receiving bus (3 3), so that each digital beamformer (3 5) can be made. The # material on the g stream can be obtained at the same time and processed in a parallel manner, so it can provide good operating efficiency. With the structure of the aforementioned transmitting antenna system and receiving antenna system, the amplitude and phase of each element line unit can be performed. Independently controlled, and the number of antenna units is 8 under the spatial filtering channel, as shown in the space wave pattern of the fourth figure, the display can easily achieve the effect of reducing the side lobe The spatial filter group formed by multiple digital beamformers performs multi-beam processing, and the resulting field pattern is shown in the fifth figure, which also shows that under the condition that multiple beams are performed simultaneously, each beam is maintained at In a good state, there is no problem of mutual interference, and the level of each side lobe is kept relatively low, which can fully prove the effect of the present invention. In addition, as shown in the sixth figure, when it is in the amplitude In cases where the phase error is quite large, similar effects can also be maintained roughly. It is further proved that the large error of the hardware in this case is still within the allowable range. Therefore, the requirements for the precision of the hardware are relatively low. Low hardware costs are achieved. This paper is published in 14 papers (CNS) by the government. (Please read the precautions on the back before filling out this page.)

Description of the invention (gas) Therefore, according to the description, it can be known that the intelligent antenna system of the fate gate and the inter-filter filter structure of the present invention can simultaneously perform multi-beam parallel processing to reduce the complexity of software and hardware. In addition to the advantages of the degree, it can be used by the antenna controller = each space wave in the space wave wave group $ (number of 4 vertical beamformers) to perform a parameter, or preset zeroing and close unused channels in a timely manner. Order to make the actual use more flexible changes and reduce the advantages of noise interference and improve the quality of communication 'is indeed a new I-membership and in line with the industrial use of the invention, should meet the requirements of patent applications, and apply according to law. -44- This paper size applies to China National Standard (CNS > A4 size (210x297 mm)
