A receiving-apparatus which includes space-filtering-unit configured to separate receive-signals into signal of first-data-sequence and signal of second-data-sequence on basis of estimation result, provisional-decoding-unit configured to LDPC-decode the two corresponding signals, to obtain provisional-likelihood-ratio for the two sequences, provisional-output-unit configured to output two provisional corresponding sequences on the basis of the respective provisional-likelihood-ratio, replica-signal-generation-unit, estimation-result of propagation-path-estimation-unit, soft-decision-outputting-unit configured to obtain receive-likelihood-values of the two sequences, on basis of residual-signal obtained by subtracting replica-signal from receive-signals, actual-decoding-unit configured to LDPC-decode receive-likelihood-values, to obtain likelihood-ratio of the two sequences, and actual-output-unit configured to obtain the two sequences on the basis of likelihood-ratio of the two sequences to hard-decision.
