A receiving apparatus and reception method reduces 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, using the symbol replica generated by symbol replica generator and the channel estimate which a channel estimator estimated based on the received pilot signal, suppresses interference attributed to delayed waves exceeding the GI and outputs a suppressed signal for the received signal. A demodulator decodes the signal of which interference has been alleviated, to determine code bit LLR as bit likelihood information. A decoder 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. |
