PROBLEM TO BE SOLVED: To provide a receiver and a receiving method, which have successful characteristics even when noise enhancement occurs in linear detection and efficiently calculate a bit LLR (Log Likelihood Ratio) in an MIMO (Multiple Input Multiple Output) transmission system.SOLUTION: A signal detection part 203 detects separation of spatially multiplexed signals using a received signal and a propagation path estimated value estimated by a propagation path estimation part 204, and obtains coded bits LLR by making an inversion bit sequence remain in transmission signal candidates. The coded bits LLR, which are obtained by the signal detection part 203, are input in decoding parts 206-1 to 206-T by returning rearrangement performed in interleaver parts 103-1 to 103-T on the transmitting side by deinterleaver parts 205-1 to 205-T. In the decoding parts 206-1 to 206-T, error correction decoding is performed on the input coded bits. Parallel/serial conversion is performed on the bit sequence after the error correction decoding by a parallel/serial conversion part 207, and a transmission bit sequence is output. |
