[Prior Art] The increase in the number of mobile users has maintained a high call quality while increasing the capacity of the service, which has become a demand for modern mobile communication systems. Smart antenna technology is just the leading technology for modern mobile communication technology orders. Smart antenna technology (also known as array antenna technology) usually uses two or more single antenna elements to form an antenna array. The weight of the number 7 received by each array element is adjusted by appropriate weights to adjust the reception. The phase and amplitude of the signal, such that after the weighted summation of the received signal, the desired signal is enhanced and the interfering signal is attenuated. The weighting is essentially a spatial filtering. According to the research table, smart antenna technology can effectively improve the signal noise 2, which can significantly improve the quality of the call during communication. However, the mobile terminal of the existing through 2 system generally adopts a processing module for the single antenna system. If the smart antenna technology is applied to the existing mobile terminal, the more flexible and soft parts of the processing module need to be redesigned. The cost will be very expensive. For example, it can be implemented on the basis of mobile terminals to effectively utilize the hardware and software resources of the single antenna system to process the model money. A key issue for the application of the antenna is applied to the mobile terminal.

In the downlink, first, in the RF module 101, the wireless signal received by the antenna 100 is amplified and down-converted, and converted. The intermediate frequency signal or the analog fundamental frequency signal; then, after being sampled and quantized in the ADC/DAC module 102, the intermediate frequency h or analog baseband signal is converted into a digital baseband signal and input to the fundamental frequency physical layer processing. The module 103; in the baseband physical layer processing module 103, according to the control signal from the baseband control module 104, the digital baseband L number After Rake reception, despreading, demodulation, deinterleaving, joint detection (JD), Viterbi/Turbo decoding, etc., the obtained signal is provided to the baseband layer processing module 105; In the processing module 1〇5, the data processed by the baseband physical layer processing module 〇3 is subjected to data link layer network layer or more layer processing, including high layer signaling processing, system control, and source coding. /decoding, etc. Currently, the above single-antenna mobile phone technology is quite mature, including Philips.

O:\89\S9801.DOC -6- 1358917 Many manufacturers, including Division A, have developed mature chipset solutions. Wherein, the function of the above-mentioned baseband physical layer processing module 1〇3 is usually achieved by a baseband data machine composed of an application-specific integrated circuit (ASI0). However, if the smart antenna technology is introduced in the existing mobile phone, it will be completely changed. The entire baseband physical layer processing module is set up, and its hardware and corresponding software 'such as standard design Rake receiver and despreading frequency will be difficult to use. To use. Not to know the design of the fundamental frequency system, - CS company ( An electronic device company in Los Angeles, California, USA provides a mobile phone device for introducing a smart antenna as shown in Fig. 2. As shown in Fig. 2, the SA module 206 is composed of an antenna combiner 208 and a combined control module 207. In the configuration, the merge control module 207 adjusts two sets of the antenna combiner 2〇8 according to the feedback signals output by the Rake receiver & despreading module 209 and the Viterbi/Turb〇 decoder module 21〇. The antenna combiner 208 combines the input signals of the two channels by multiplying the control signals provided by the merge control module 2〇7 by a set of weights. In this scheme, wisdom Building line module module 206) and Rake receiver are separated, i.e. space diversity and time diversity lines were reached, and therefore the standard baseband processing system software can be reused. However, since the merge controller 207 in the SA module 206 needs to use the dynamic feedback signal from the Rake receiver & despreading module 209 and the Viterbi/Turbo decoder module 21〇 to control the adjustment antenna combiner 208 The operation of the combined controller 207 and the Rake receiver & despreading module 209 and the Viterbi/Turbo intermodulation module 210 is incompatible with the standard baseband physical layer processing module, resulting in Standard

Therefore, if the above-mentioned design of Innovations is adopted, it is necessary to change the design of the standard system, that is, to redesign the fundamental frequency physical layer processing module 1〇3 to support the SA module 206, which is very difficult. In summary, in terms of reusing the existing mobile terminal design, the original technology only achieved the design of reusing its software, but it is not possible to reuse both the software and the hardware design at the same time. Therefore, how to base the existing mobile terminal The implementation of the improvement to effectively utilize the hard-call and software resources in the processing module of the single-antenna system is still an unsolved problem of applying the smart antenna to the mobile terminal.

As shown, the device includes two sets of RF signals consisting of two antennas 300, two frequency-receiving modules 3 0!, and two ADC/DAC modules 3〇2.

The SA module (smart antenna module) 306 at the output end is used for implementing the smart antenna baseband processing for each digital baseband signal; and a baseband physical layer processing module 303' is used for processing by the sa module. The digital signal performs basic frequency signal processing, which may include: Rake reception, despreading, demodulation, deinterleaving Joint detection _, Μ-.

As can be seen from FIG. 3, the SA module 306 is a separate module, and the modulo b needs to use the dynamic feedback signal from the baseband physical layer processing module 303, and is based on the SA 帛 group startup by the data bus. - Sub-provided SA control commands to achieve the baseband processing of the smart antenna. Among them, via

O:\89\89801.DOC -10· 1358917 The SA control commands transmitted by the data bus to the SA module 306 may include, but are not limited to, an enable signal, an algorithm selection signal, and a downlink pilot time slot data ( DwPTS) and training sequence data (Midamble), etc., and the SA control command can be transmitted to the SA module 306 via the data bus, or can be transmitted to the SA module 306 through other interfaces. 3. If the system is TD-SCDMA, In the operation of the smart antenna receiving device shown in FIG. 3, if the SA module 3〇6 can reuse the synchronization function of the baseband physical layer processing module 303, the physical layer of the baseband must be obtained when the sA module is initialized. Processing the synchronization information of the module 3〇3. The operation process of the normal smart antenna baseband processing after the SA module first acquires the synchronization information in the system employing the TD-SCDMA will be described in detail below with reference to FIG. As shown in FIG. 4, the sa module 306 includes two buffers 3〇8 whose input terminals are respectively connected to the output ends of the ADC/DAC module 3〇2, and are used for buffering when processing downlink data. The digital baseband signal obtained by the ADC; two weight adjustment modules 309, 309, which respectively weight the data output by the two buffers 308 according to the weight information received by each; For example, the adder 310) is configured to combine the two weighting adjustment modules 3〇9, and the outputted weighted data, and output the merged data to the baseband physical layer processing module 303. ;-controller (such as merge and synchronous control (4) 3〇7), which receives the above ADC/DAC module 3〇2 input to the data information of the two buffers, and according to the SA control command from the data bus and Privately using a simple sub-frame and time slot synchronization method to achieve synchronization of the data stream that is rotated into the UI module 306, while controlling the weight adjustment mode and the trace,

The weight of O:\89\89801.DOC 1358917. The specific operation process is as follows: First, the SA module 306 forest [• know pull, π stop smart antenna base frequency processing operation, at this time, the SA module can receive the signal transmitted by the single-channel early RF signal processing module, That is, for a single RF signal processing mode torsion value,,,,, and the transmitted signal, the 8 octave, and 306 can be regarded as a path, which is established between the mobile phone and the base station. After the connection, the f-frequency physical layer processing module 303 will first obtain the k-axis and the right-hand-down link pilot time slot and the user-specific training sequence of the k-number input through the single-channel radio frequency signal processing module. After the baseband processing module obtains one of the downlink pilot time slot and the user-specific training sequence SA control command obtained by the baseband physical layer processing module, the SSA module 3 is transmitted via the data bus. 〇6, and the SA module 3〇6 is activated by the driving signal in the SA control command; Third: in the SA module 3〇6 driven by the data, the synchronizing controller in the combining and synchronizing controller 307 is used. The downlink key frequency slot in the SA (four) command matches the input signal to achieve Frame synchronization; Fourth: After the completion of the subframe synchronization, the synchronization controller of the combination and synchronization controller 3〇7t uses the user-specific training sequence in the SA control command to match the input signal, so that the base station The specified downlink slot synchronization; Fifth: After the downlink slot synchronization is achieved, the location of the training sequence of the received slot can be determined. The merge and synchronization controller 307 is based on the training sequence obtained from the received time slot and the user-specific training sequence (as a reference signal) included in the SA control command from the baseband physical layer processing module 303. The combined controller performs the O:\89\8980I.DOC •12· 1358917 algorithm according to the weight specified in the SA control command, and calculates the corresponding weights, and provides the calculated weights to the two weight adjustment modules. 309, 309,; eighth, in the weight adjustment kernel group 309, 309', the buffer data output by the two buffers 308 are respectively multiplied by the corresponding weights obtained in the above step 5 and the weighted data is input. In the adder 310; seventh: the merged data in the adder 310 is transmitted to the subsequent baseband physical layer processing module 3 〇3. 8. Repeat steps 3 through 7 above, s A mode and process the input signal in such a pipeline manner. In the above operation process ten, the following points need to be specifically explained: h Since the SA module is prohibited from being operated at the beginning in the above step 1, only the SA module receives the SA control life from the data bus in step 2 7 (The SA command contains synchronization information for synchronizing the input signals: the downlink keyway time slot and the user-specific training sequence and the start signal and weight algorithm selection signal for starting the SA module job), SA The Mo group side starts the operation by the data driver's. That is, the SA module acquires the synchronization information before its security. Therefore, the SA module can reuse the synchronization function of the baseband physical layer processing module 303 without conflict. 2. In the above steps 3 and 4, 'the sa module adopts a simplified sub-frame synchronization and time slot synchronization method. The reason for this simplicity is that the 5乂 method is the transmission signal of the TD_SCDMA system. The frame structure is determined; the frame structure of the transmitted signal in the TD SCDMA system will be described in detail in conjunction with _5•Bu 5_2'5_3 and 5_4. As shown in Figure 51, the frame used in the Td_Scdam system is from top to bottom.

O:\89\89801.DOC -13- consists of four layers: 'super-frame, radio frame, sub-frame, and time slot (time) Sl〇t). The length of each super frame is 720 milliseconds, including 72 RF frames; each RF frame is 103⁄4 seconds. The RF frame is divided into two sub-air frames. Each subframe is 5 in length. In milliseconds, in the RF frame with a length of 1 millisecond, the frame structure of each subframe is the same. The use of a 5 millisecond subframe structure facilitates fast power control, uplink key synchronization, and beamforming. β can also be seen in Figure 5-1. Each subframe further includes 7 traffic timeslots and 3 traffic slots. Specific time slot (speciai timesi〇t). TS0-TS6 in the figure are service slots, DwPTS (downlink pilot slot), UpPTS (uplink pilot slot), and GP (guard period) are three specific slots. The structure of the downlink pilot time slot (DwPTS) and the uplink pilot time slot (UpPTS) is further described in FIG. 5-2 and FIG. 5-3, wherein the SYNC-DL block in FIG. 5_2 and FIG. 5 The SYNC-UL column in -3 is used for frame downlink or uplink pilot in frame synchronization, respectively. A bursting structure of a service time slot (T0-T6) is further described in FIG. 5_4. As shown in the figure, a training sequence (ie, a midamble) is located between service time slots, and its position is fixed, and the training sequence is The length is 144 chips. For different communication cells, the codes of the training sequences are different from each other (ie, different training sequence sets are used). In TD-SCDMA, the training sequence is also used. In the smart antenna algorithm. As described above with reference to FIGS. 5_1 to 7·4, since the structure of each subframe in each RF frame is the same in the system using TD-SCDMA, the input RF can be achieved by using the subframe synchronization method in the third step. Signal synchronization; same

O:\89\89801.DOC • 14- 1358917. Because the training sequence in the input signal is used in the system using td-SCDMA, the receiving weight of the smart antenna is calculated, and the position of the training sequence in the input signal is Fixed, so in step four, using the slot synchronization method, the training sequence of the input signal can be further obtained to calculate the weight of the smart antenna. 3. Since in the above steps 3 and 4, the SA module adopts such a simplified subframe synchronization and slot synchronization method, and the method (ie, downlink pilot time slot and user specific) The training sequence is obtained by the slave module from the baseband physical layer processing module 3〇3. Therefore, it is not necessary to perform a search operation of the downlink pilot time slot and the user-specific training sequence, and the downlink is used for feedback correction. The pilot slot and the user-specific training sequence match the rounding apostrophe to achieve the sub-frame and slot synchronization of the input signal. Compared with the entire synchronization process performed in the baseband physical layer processing module, the sa amount of the (fourth) construction and the synchronization method of the present invention is executed during the execution of the sub-frame synchronization process t at most | 31/32 (four). Up to 1 5/16 of the time can be saved during time slot synchronization.

(As mentioned above, since the training sequence used as the smart antenna in the TD_SCDMA system is in the middle of the time slot (as shown in Figure 5-4), two buffers are used in the 'SA module 306 to buffer the received one. The signal, ie, = buffers the received signal until the training sequence of the current time slot is obtained, and then performs the next processing. The distance between the above-mentioned subframe synchronization and the two smart antennas of the time slot signal is very small, so The signals received by the two channels arrive almost simultaneously. Assuming that the two channels are synchronized with each other, the above-mentioned subframe synchronization and O:\89V8980J.doc -15-slot synchronization can be performed only in one channel A. The SA module structure shown in Fig. 4 is also applicable to the uplink mode. The above-mentioned smart antenna receiving apparatus and receiving method of the present invention only need to insert the A SA module in the existing single-antenna mobile phone without the need for the hardware of the existing mobile phone. And the software design implementation can be greatly improved to achieve (4) the combination of antenna technology and mobile phone. However, the inserted SA module will certainly have an impact on existing components such as the baseband physical layer processing core group 3〇3, especially It is the delay caused by the buffer 3G8 in the SA module, which is a problem to be considered in the implementation of the present invention. In the design process of the present invention, some predefined parameters are set in the fundamental frequency physical layer processing 03 for a long time. Reflecting the delay caused by the buffer, these delays mainly lead to two problems: (1) closed-loop control, including power control, automatic gain control (AGC), automatic frequency control (eight? (:), etc. power control system The closed-loop control between the base station and the mobile phone, the highest frequency is Hertz', that is, at most every sub-frame execution-time power control, the processing power control time is almost a sub-frame. If caused by the SA module The processing delay is -ai P* ( 1 /-» horse time slots (about 1/7 sub-frame), it is difficult to affect power control. AGC and AFC are closed-loop control in mobile phones. 'Unspecified in td_scdma standard' The design of the AGC and WCDMA data machines, under the condition 'the response time of the AFC by the SA module 3〇6, but according to the current response time is a time slot. The processing delay in this way will lead to the decline of the performance of the mobile phone. Therefore, the inch is used to reduce the effect. By further reducing the size of the two buffers 308

O:\89V89801.DOC -16· (2) Uplink synchronization. In a system using TD-SCDMA, it is necessary to: 仃 link synchronization before the random access procedure. This requires the base station to maintain and synchronize when receiving signals from different users. The process and description are defined as follows: y, a. First synchronize the downlink;

The set-end terminal transmits an uplink pilot time slot, and then the base station transmits adjustment information; Dc • uses a training sequence to maintain uplink synchronization; d. synchronization accuracy is 1/8 chip. + Due to the processing of the SA group 306 and the baseband physical layer processing module 3〇3, it is desirable to accurately maintain the uplink key synchronization. The case of the two consecutive sub-frames of the processing delay of the SA module is as shown in Fig. 6. For frames following the slave module 306, only the downlink time slots are of interest. #中,加 indicates the first time slot of the subframe; PTS indicates the uplink key pilot time slot 1 line pilot (4): 丨 and 丨 indicate the uplink and downlink links, respectively. As can be seen from Figure 6, the data frame after the SA module 3〇6 is delayed by a gap. The uplink time slot is indicated in the previous frame. The baseband physical layer processing module 303 is required to process both downlink and uplink data (as indicated by the dotted line) and the 5't SA module 306 is processing the time slot Ts and sending the corrected data to the baseband. When the physical layer processing module is 3〇3, the baseband physical layer processing module 303 is also processing TS1. Therefore, the baseband physical layer processing module 303 is required to support parallel processing of the uplink key and the downlink key data. According to the design of the WCDMA baseband data machine, parallel processing of the uplink and downlink data does not conflict. Fundamental frequency physics in the HD-SCDMA standard

O:\89\89SOI.DOC •17· 1358917 The layer processing module 303 is designed to be similar to WCDMA, so there is no conflict. In view of the delay caused by the above buffer, the present invention provides an example of a smart antenna receiving apparatus for a mobile phone. In this example, two looped first in first out (FIFO) memories are employed as buffers in the SA module described above. The specific structure thereof will be explained in the following description in conjunction with FIG. FIG. 7 is a structural diagram of an embodiment of the S A module shown in FIG. 4. In this embodiment, the buffer 308 is a two-ring FIF buffer 3〇8, which is one slot in size. The other modules disclosed in FIG. 7 are the same as the corresponding modules shown in FIG. 4, and thus are not described herein again. It should be noted that the SA module 3〇6 can be achieved in this manner, but should not be limited to this. The processing steps of the SA module shown in FIG. 7 will be described below with reference to FIGS. 8, 11, and 12. (1) The SA module 306 is prohibited from operating using an omnidirectional beam before establishing a connection or when the SA performance cannot meet the requirements. . The SA module 306 is disabled by the "fundamental frequency control" module. At this time, the signal of channel 1 passes 'and the signal of channel 2 is suppressed. The received signal is first buffered in two circular FIF0 buffers 308, and sent to the lower-module when the circular fifc buffer 3G8' is full. The data stream is delayed by a time slot. Its structure is shown in Figure 8. (2) starting the SA module 306 operation, after the connection has been established and obtaining the downlink pilot time slot and the training sequence from the baseband processing module via the data bus, the 'base frequency control module starts the SA module 306, and then The downlink keyway time slot is used to implement the synchronization of the O:\89\8980I.DOC -18·1358917 subframe. Its structure is shown in Figure 9. (3) Synchronizing the sub-frames The sub-frames are synchronized by matching the downlink pilot time slots with the received signals of channel i, and then matching is performed using the training sequence to synchronize the downlink time slots. (4) Synchronizing the downlink time slot after using the training sequence to synchronize the downlink time slot, using the received training sequence and the training sequence obtained from the baseband physical layer processing module 303 transmitted via the data bus. To calculate two weights (five), w2). (5) Combine All data of the current time slot is buffered in the ring fif buffer 3〇8 when the previous time slot (if any) is processed. The cached data is combined by multiplying the corresponding weights, and the merged data is sent to the next module. (6) Repeat steps (3)-(5) The SA module processes the received data stream in this pipeline mode. Figure 10 shows the timing when the SA module 306 is not initialized. Wherein, the sub-frames 〇 and 1 indicate the received first and second sub-frames; respectively indicating the uplink and the downlink; and indicating that the time slot is being used by the two downlink time slots of each channel Consolidation. Advantageous Effects As apparent from the above description of the present invention with reference to the accompanying drawings, it can be clearly seen that a downlink keyway pilot time slot for data synchronization and weight calculation in a separate SA module inserted in an existing mobile phone, The training sequence and other signal systems are acquired when the SA module is started, so the independent module can be heavy.

O:\89\89801.DOC -19· 1358917 Reuse the software and hardware design of the standard baseband physical layer processing module without major changes. At the same time, in the SA module of the present invention, the SA module operation is first disabled, and the SA module operation is started after the connection is established and the synchronization information is transmitted to the SA module via the data bus. Therefore, the conflict between the execution of the SA module operation and the reuse of the baseband physical layer processing module function is ingeniously avoided. In addition, in the SA module of the present invention, since a simple sub-frame synchronization and slot synchronization method is adopted, especially the synchronization information is directly obtained from the SA control command, and the mother needs to search for the downlink pilot time slot and training. The sequence thus significantly reduces the time required to synchronize the input data, greatly improving the performance of the communication system.
