摘要： To obtain excellent reception performance whilst cutting down the amount of computing operation in a MIMO communication system using soft-decision error correction coding. Received waves picked up by receiving antennas 401-1 to 401-R are converted from the radio frequency to the baseband signal by respective receivers 402-1 to 402-R to be output as a received signal. A signal detector 403 calculates bit LLRs of the transmitted signal based on the received signal and the channel-estimated values obtained from a channel estimator 404. The bit LLRs output from signal detector 403 are rearranged by deinterleaver units 405-1 to 405-T in the patterns opposite to the patterns in which interleaving was performed on the transmission side. The bit LLRs after de-interleaving are subjected to an error correction decoding process through decoders 406-1 to 406-T. The bit sequences after decoding are parallel-to-serial converted by a parallel-to-serial converter 407 so that the detected transmission bit sequence is output.

摘要： To provide a receiving apparatus and reception method that can reduce degradation due to multipath interference without increasing the amount of computation even in a system that has a large number of subcarriers.
A signal detector 205, using the symbol replica generated by symbol replica generator 208 and the channel estimate which a channel estimator 209 estimated based on the received pilot signal, suppresses interference attributed to delayed waves exceeding the GI and outputs a suppressed signal for the receivedsignal. Ademodulator 206 decodes the signal of which interference has been alleviated, to determine code bit LLR as bit likelihood information. A decoder 207 performs an error correction decoding process on the input code bit LLR. If no error exists in the result of error correction decoding, the decoder outputs information bits to complete the reception process. If there is an error in the decoded result, the decoder outputs the code bit LLR to symbol replica generator 208.摘要翻译： 提供即使在具有大量子载波的系统中也可以减少由于多路径干扰导致的劣化而不增加计算量的接收装置和接收方法。 信号检测器205使用由符号复制产生器208产生的符号副本和信道估计器209基于接收到的导频信号估计的信道估计，抑制归因于超过GI的延迟波的干扰，并输出用于接收到的信号的抑制信号。 调制器206解码已经减轻了干扰的信号，以将码位LLR确定为比特似然信息。 解码器207对输入码位LLR进行纠错解码处理。 如果在纠错解码结果中没有错误，则解码器输出信息比特以完成接收处理。 如果在解码结果中存在错误，则解码器将码位LLR输出到码元副本生成器208。

摘要： By controlling to select encoding appropriately considering characteristics of equalization and decoding of a receiving apparatus employing a turbo equalization technology, it is possible to attain a high transmission characteristic. Information bits of two systems including a sequence which is input to a first RSC encoding unit 22 and a sequence which is input through an interleaving unit 21 to a second RSC encoding unit 23 are set for input information bits, and each of which is subjected to RSC encoding. Each encoded parity bit is input to a puncturing unit 24. Since a systematic bit obtained by the first RSC encoding unit 22 is the information bit itself, a systematic bit obtained by the second RSC encoding unit 23 is not transmitted. In the puncturing unit 24, while puncturing is applied according to a predetermined coding rate, selection of either an RSC code or a turbo code is carried out by a puncturing control unit 25.
