BACKGROUND The Long Term Evolution (LTE) protocol specifies the sequence of bit-level processing of uplink transmitters. To maintain consistency, the receiver uses the Turbo-SIC algorithm for data reconstruction. Corresponding processing techniques to ensure the correct output of the signal. As shown in Figure 1, the protocol specifies the techniques of channel interleaving, scrambling, and modulation at the bit level of the LTE transmitter; therefore, the corresponding receiving end needs to perform channel interleaving, scrambling, and modulation when using the Turbo-SIC algorithm. The processing order corresponds to it. Since the LTE receiver uses the Turbo-SIC algorithm for data reconstruction, in order to ensure the wireless performance of the receiving end, usually the soft bit information output by the Turbo decoder for reconstruction needs a relatively large bit width, according to the order of the originating end. The processing sequence of signal interleaving, scrambling, and modulation needs to be performed. Since the channel interleaving needs to wait until all the data is collected, the scrambling and modulation processing can be performed. This processing method increases the random access memory of the system (Random). The use area of Access Memory (abbreviated as RAM) makes the design take up a lot of RAM resources. Aiming at the problem that the data reconstruction method in the related art causes the utilization of the system storage resource to be relatively low, an effective solution has not been proposed yet.

3种调制方式 QPSK、 16QAM和 64QAM以 2、 4和 6路并行输出数据，同时将扰码序列从扰码存储模块的緩存中读取，与数据对齐后进行加扰和软调制处理，由于加 4尤和软调制处理都以资源单元（Resource Element, 简称为 RE ) 为单位进行，因此软调制完成之后得到 RE符号（ IQ数据）步骤 S406：软速率匹配模块对译码后的数据进行软速率匹配。步骤 S408: 判断信道交织 RAM UCI数据是否填完，如果判断结果为是，执行步 4聚 S418, 如果判断结果为否，执行步 4聚 S410。需要说明的是，造成 RAM资源过大的原因在于 Turbo译码核输出的软比特位宽较大，而信道交织需要收齐一个用户的所有软比特后才能完成其功能，所以需要进行緩存。因此解决问题的核心在于保证***性能（也就是不牺牲软比特位宽）的前提下，进行优化***结构，从而达到减少 RAM资源占用。步骤 S412: 4尤码生成模块生成 4尤码。步骤 S414: 将生成的扰码存入解信道交织模块进行处理。步骤 S416: 将解信道交织模块处理后的数据存入 4尤码存储模块。需要说明的是，原协议中信道交织之后，数据的顺序被打乱，则加扰时扰码不能按照协议规定的正常生成顺序生成，并对数据进行加扰。本实施例中步骤 S416将扰码存放在解信道交织的緩存之中，当解信道交织输出时，将输出的扰码序列单独进行緩存。由于信道交织和解信道交织对一个用户来说是完全对称相逆的操作，因此加 4尤时可以使用上述方法产生的 4尤码。另外一种方式是单独产生扰码，并将其进行信道交织，但是这种方法需要另外耗费硬件资源来实现，实现成本比较高。步骤 S418: 将扰码存储模块存储的扰码和填完信道交织 RAM UCI的数据送入加 ^尤模块进行处理。步骤 S420：将加 4尤模块处理后的数据送入软调制模块进行处理。步骤 S422: 将软调制模块处理后的数据送入信道交织模块进行处理。需要说明的是，占用大量 RAM资源的是信道交织，而信道交织后的加扰和软调制模块是流水处理的，所以可以把信号交织、加扰和软调制作为一个整体来分析。考虑到软比特进行软调制以后位宽会降低很多，通过上述步骤 S418 至步骤 S422, 将加扰和软调制模块放到信道交织模块之前的处理方式，会显著降低 RAM的占用资源，并且对***的整体时延和无线性能均无损失。同时，将扰码生成模块产生的扰码序列按照 UE占用的时频资源，与数据一同存入解信道交织的緩存进行解信道交织操作后，依次存入扰码存储模块的緩存中，存储时只保留数据位置的扰码， UCI位置扰码不进行存储，确认（ ACK ) 与数据重合位置的扰码和存储数据均置为零，另外扰码序列和数据的存储均按照 RE为单位。步骤 S424: 判断 ACK位置数据是否置零，如果判断结果为是，执行步骤 S428, 否则，执行步骤 S426。步骤 S426: 等待信道交织 RAM ACK位置数据置零完成。步骤 S428: 将 ACK置零后的数据送入离散傅立叶变换模块处理。具体地，将信道交织 RAM中 RI、 CQI位置的数据按照 UCI时频资源进行添零处理，然后将软调制得到的 RE数据符号存入信道交织的 RAM中，若当前用户存在 ACK,则对 ACK位置的数据用零进行覆盖。对存入信道交织 RAM 中的数据按照协议进行信道处理，并完成 CB到 TB数据的合并。步骤 S430: 数据重构处理结束。具体地，将完成信道交织的数据进行离散傅立叶变换（DFT ) 变换和千扰抵消处理，完成 Turbo-SIC算法中数据的重构过程， DFT变换的点数为用户所占用的子载波数目。实施例三本实施例提供了一种数据重构方法，本实施例结合了上述实施例及其中的优选实施方式。在本实施例中， LTE***为频分双工（FDD ) 20M带宽，当前用户所占 RB个数为 100, 上行釆用 2x4的多用户-多输入多输出（ MU-MIMO ) 传输模式，配对的两用户标 ΐ己为 U1和 U2;其中基站釆用 4天线接收，调制方式为 64QAM, 循环前缀（CP ) 类型为 normal CP, 无 sounding导频信号，无物理上行控制信道（ PUCCH ) 信道，有上行控制信息（ Uplink Control Information, 简称为 UCI ) (包括 RI、 CQI/PMI和 ACK ), 釆用 Turbo-SIC算法进行 MU-MIMO用户的数据解析。图 5是根据本发明优选实施例的数据重构方法流程图二，如图 5所示，该方法包括如下步骤：步骤 1 :基带上行接收 RRU发送的 4天线的基带 IQ数后緩存，经过 OFDM 解调处理后，对 symbol 3和 10上的导频信号进行信道估计和物理层的相关测量，并用估计出的信道估计值对其他 symbol 的数据位置完成信道估计，将信道估计值和 IQ数据送入均衡模块，同时启动 4尤码生成模块进行 4尤码初值的计算；步骤 2: 均衡模块使用 MMSE算法完成数据均衡和天线合并的功能，得到两路数据 U1和 U2; 对 U1和 U2分别进行 1200点的 IDFT变换，同时 4尤码生成模块产生 IDFT变换后对应数据的 6 bit扰码，将 IDFT变换后的数据与其对应的 6 bit扰码进行拼接到并存入解信道交织的 RAM中进行緩存；步骤 3 : 先对 U1路数据进行处理，将解信道交织模块 RAM中緩存的 U1 数据进行解信道交织处理，并对处理后的数据进行解调，得到 48 bit的软比特，然后对软 bit数据进行解扰，其中每 8个软 bit数据对应 1个扰码 bit。解调解扰的处理均为流水处理，解扰后的数据按照每 cycle 6bit的格式送给解速率匹配模块。需要说明的是，需要将解信号交织后的扰码序列送给加扰软调制模块进行緩存，緩存的顺序按照解信道交织模块的输出顺序；步骤 4: 经过解速率匹配处理后，数据分成 3路，同时送入 Turbo译码核中进行 Turbo迭代译码，进行合适的迭代次数后，得到没有进行判决的 3路 LLR 软比特数据。对 LLR软比特数据进行软速率匹配后，得到一路 LLR软比特数据，并送给加扰软调制模块，其中 LLR数据发送给加扰软调制模块的格式为每 cycle 6个 LLR软比特数据；步骤 5 : 从扰码緩存 RAM中读取 6bit的扰码序列对 6个 LLR软比特数据进行加扰操作，然后对加扰后的 6个 LLR软比特数据按照 64QAM的调制格式进行软调制，得到一个复值符号并送给信道交织模块，其中加扰和软调制模块均为 ¾i水处理；步骤 6: 信道交织模块首先需要将信道交织 RAM 中 UCI (包括 RI 和 CQI/PMI )位置的位置填 0,处理完成后将加 4尤软调制模块的输入数据跳过 UCI 的位置依次存入信道交织 RAM, 当前用户的所有数据存完后，再将 RAM 中 ACK的位置置零，完成后对信道交织 RAM中的数据进行信道交织处理，完成后送给 DFT处理模块；步骤 7: 对数据进行 1200点的 DFT变换，然后与 OFDM解调模块中緩存的天线数据进行千扰抵消，得到抵消后的数据 U1' , 再对其按照行图 4中的蓝色数据处理流程得到 U2的 TB数据；步骤 8: 在 U1数据开始进行 DFT处理时，启动 U2数据的处理流程，按照步 4聚 3、 4、 5、 6和 7得到 U1的 TB数据。本实施例提供了一种数据重构装置，用以实现上述的数据重构方法，图 6 是根据本发明实施例的数据重构装置的结构框图该装置包括：加扰模块 62 , 软调制模块 64 , 信道交织模块 66 , 数据重构模块 68 , 下面对上述结构进行详细描述：加扰模块 62 , 设置为对接收到的 LTE的上行数据进行加扰操作；软调制模块 64 , 连接至加扰模块 62 , 设置为将加扰模块 62加扰操作后的数据进行软调制；信道交织模块 66 , 连接至软调制模块 64 , 设置为将软调制模块 64软调制操作后的数据进行信道交织编码；数据重构模块 68 , 设置为使用信道交织模块 66信道交织编码后的数据进行数据重构。优选地，加扰模块 62 , 设置为以软速率匹配操作后的软比特信息的有效信号作为读有效信号，将 4尤码按照緩存时的顺序依次读出，在拔 ^ 与速率匹配后的软比特信息对齐后，使用扰码对软比特进行加扰操作，其中，扰码是緩存在存储器中，通过对上行数据解扰时产生的扰码数据进行解信道交织得到。优选地，软调制模块 64 , 设置为对加扰操作后的数据釆用以下之一的调制方式进行软调制： QPSK、 16 QAM, 64 QAM。图 7是根据本发明实施例的数据重构装置的优选的结构框图，如图 7所示，该装置还包括：译码模块 72和匹配模块 74 , 信道交织模块 66包括：第一置零模块 662、填充模块 664、第二置零模块 666和编码模块 668 , 下面对上述结构进行详细说明。译码模块 72 , 设置为对数据进行译码得到软比特信息；匹配模块 74, 连接至译码模块 72, 设置为对译码模块 72得到的软比特信息进行软速率匹配。信道交织模块 66包括：第一置零模块 662, 设置为将信道交织存储器中的秩信息和信道质量信息的数据进行置零操作；填充模块 664, 连接至第一置零模块 662 , 设置为将软调制操作后的数据填充入经过置零操作的信道交织存储器中；第二置零模块 666 , 连接至填充模块 664, 设置为将填充操作后的信道交织存储器中的确认信息的位置的数据置零；编码模块 668 , 连接至置零模块 662 , 设置为对经过确认信息的位置的数据置零操作后的信道交织存储器中的数据进行信道交织编码。通过上述实施例，通过釆用调整信号重构时加扰、软调制和信道交织的先后顺序，达到了节省交织矩阵 RAM的效果。在速率匹配后的数据位宽是每个 RE 符号位位宽较大，而软调制后的数据位宽大为减少，减去扰码存储占用的 RAM资源，节省了约 60%的 RAM资源。另外，本实施例提供的方案同样适用于对 LTE协议规定的发射端的设计。显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而可以将它们存储在存储装置中由计算装置来执行，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的 ^"神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。 The three modulation modes QPSK, 16QAM and 64QAM output data in parallel with 2, 4 and 6 channels. At the same time, the scrambling code sequence is read from the buffer of the scrambling code storage module, and is aligned with the data for scrambling and soft modulation processing. 4 The special soft processing is performed in units of Resource Element (RE), so the RE symbol (IQ data) is obtained after the soft modulation is completed. Step S406: The soft rate matching module performs soft rate on the decoded data. match. Step S408: It is judged whether the channel interleaving RAM UCI data is filled out. If the judgment result is yes, step 4 is performed S418, and if the judgment result is no, step 4 is performed S410. It should be noted that the reason why the RAM resource is too large is that the soft bit width of the Turbo decoding core is large, and the channel interleaving needs to collect all the soft bits of a user to complete its function, so it needs to be cached. Therefore, the core of the solution is to ensure system performance (that is, without sacrificing soft bit width), to optimize the system structure, thereby reducing RAM resource usage. Step S412: The 4th code generation module generates 4 U.S. code. Step S414: The generated scrambling code is stored in a de-channel interleaving module for processing. Step S416: The data processed by the de-channel interleaving module is stored in the 4 U code storage module. It should be noted that after the channel interleaving in the original protocol, the order of the data is scrambled, and the scrambling code cannot be generated according to the normal generation order specified by the protocol, and the data is scrambled. In step S416, the scrambling code is stored in the buffer of the de-channel interleaving, and when the channel interleaving output is output, the output will be output. The scrambling sequence is cached separately. Since channel interleaving and de-channel interleaving are completely symmetric and inverse operations for a user, the 4 sigma generated by the above method can be used when adding 4 times. Another way is to generate the scrambling code separately and interleave the channel, but this method requires additional hardware resources to implement, and the implementation cost is relatively high. Step S418: The scrambling code stored by the scrambling code storage module and the data of the channel interleaving RAM UCI are sent to the processing module for processing. Step S420: The data processed by adding the 4 special module is sent to the soft modulation module for processing. Step S422: The data processed by the soft modulation module is sent to the channel interleaving module for processing. It should be noted that the channel interleaving is occupied by a large amount of RAM resources, and the scrambling and soft modulation modules after channel interleaving are pipelined, so signal interleaving, scrambling and soft modulation can be analyzed as a whole. Considering that the soft bit is soft-modulated, the bit width is greatly reduced. By the above steps S418 to S422, the processing method of the scrambling and soft modulation module before the channel interleaving module is performed, the RAM occupation resource is significantly reduced, and the system is There is no loss in overall latency and wireless performance. At the same time, the scrambling code sequence generated by the scrambling code generating module is stored in the buffer of the de-channel interleaving with the data, and then stored in the buffer of the scrambling code storage module, and stored in the cache. Only the scrambling code of the data location is reserved, the UCI location scrambling code is not stored, and the scrambling code and the stored data of the acknowledgment (ACK) and the data coincidence position are both set to zero, and the scrambling code sequence and data are stored in units of RE. Step S424: It is determined whether the ACK location data is set to zero. If the determination result is yes, step S428 is performed; otherwise, step S426 is performed. Step S426: Waiting for the channel interleaving RAM ACK position data to be zeroed. Step S428: The data after the ACK is set to zero is sent to the discrete Fourier transform module for processing. Specifically, the data of the RI and CQI positions in the channel interleaving RAM is subjected to zero processing according to the UCI time-frequency resource, and then the RE data symbol obtained by the soft modulation is stored in the channel interleaved RAM. If the current user has an ACK, the ACK is performed. The location data is overwritten with zeros. The data stored in the channel interleaving RAM is subjected to channel processing according to the protocol, and the CB to TB data is merged. Step S430: The data reconstruction process ends. Specifically, the data of the channel interleaving is subjected to discrete Fourier transform (DFT) transform and interference cancellation processing to complete the data reconstruction process in the Turbo-SIC algorithm, and the number of points of the DFT transform is the number of subcarriers occupied by the user. Embodiment 3 This embodiment provides a data reconstruction method. This embodiment combines the above embodiments and preferred embodiments thereof. In this embodiment, the LTE system is a frequency division duplex (FDD) 20M bandwidth, the current user occupies 100 RBs, and the uplink uses 2x4 multi-user-multiple input multiple output (MU-MIMO) transmission mode, pairing The two user labels are U1 and U2; the base station is received by 4 antennas, the modulation mode is 64QAM, the cyclic prefix (CP) type is normal CP, there is no sounding pilot signal, and there is no physical uplink control channel (PUCCH) channel.

The cache is performed; Step 3: The U1 data is processed first, and the U1 data buffered in the channel interleaving module RAM is decomposed and interleaved, and the processed data is processed. Is demodulated to obtain soft bit 48 bit, and then the descrambled soft bit data, wherein each 8 bit data corresponding to a soft scrambling code bit. The processing for solving the mediation disturbance is pipeline processing, and the descrambled data is sent to the de-rate matching module in a 6-bit per cycle format. It should be noted that the scrambling code sequence after the signal deinterleaving needs to be sent to the scrambled soft modulation module for buffering, and the order of buffering is in accordance with the output order of the de-channel interleaving module; Step 4: After de-rate matching processing, the data is divided into 3 The circuit is simultaneously sent to the Turbo decoding core for Turbo iterative decoding, and after a suitable number of iterations, three LLR soft bit data without decision are obtained. After performing soft rate matching on the LLR soft bit data, the number of LLR soft bits is obtained. And sending to the scrambled soft modulation module, wherein the format of the LLR data sent to the scrambled soft modulation module is 6 LLR soft bit data per cycle; Step 5: reading the 6-bit scrambling code sequence from the scrambling buffer RAM Six LLR soft bit data are scrambled, and then the scrambled 6 LLR soft bit data is soft modulated according to the 64QAM modulation format to obtain a complex valued symbol and sent to the channel interleaving module, where scrambling and soft modulation The modules are all 3⁄4i water treatment; Step 6: The channel interleaving module first needs to fill in the position of the UCI (including RI and CQI/PMI) positions in the channel interleaving RAM, and the input data of the 4 soft modulation module will be skipped after the processing is completed. The location of the UCI is sequentially stored in the channel interleaving RAM. After all the data of the current user is stored, the position of the ACK in the RAM is set to zero. After completion, the data in the channel interleaving RAM is interleaved and processed, and then sent to the DFT processing module. Step 7: Perform 1200-point DFT conversion on the data, and then perform interference cancellation with the antenna data buffered in the OFDM demodulation module to obtain the offset data U1', and then follow the blue in FIG. According to the TB of data processing flow obtained U2; Step 8: DFT processing starts when data of U1, U2 data processing flow starts, TB data obtained as described in step 4 of U1 poly 3, 4, 5, 6 and 7.
