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： An OFDM receiver includes an offset compensator (14) compensating for a frequency offset in a received OFDM signal. The offset compensator (14) includes a memory (51) storing two reference signals corresponding to arbitrary portions in the start symbol of the OFDM signal. A cross correlation value between the received OFDM signal and each of the two reference signals is calculated by a cross correlator (52, 53). Each peak position is detected by a peak detector (54). A frequency offset estimate value of the received OFDM signal is estimated by a frequency offset estimation circuit (55) based on the cross correlation value at each detected peak position. A phase rotation circuit (37) compensates for the frequency offset of the received OFDM signal based on the estimated frequency offset estimate value.

摘要： In a case that a CQI table applied to interpret a CSI report is changed from a first CQI table including modulation schemes up to 64QAM to a second CQI table including modulation schemes up to 256QAM, information on a CQI table selection indicating applicability of the second CQI table and a CSI subframe set indicating subframes for which a CQI table selected in the CQI table is used are transmitted. In a case that the CQI table applied to interpret the CSI report is changed from the second CQI table to a third CQI table including modulation schemes up to 1024QAM, only the information on the CQI table selection indicating applicability of the third CQI table is transmitted.
