PROBLEM TO BE SOLVED: To provide a signal-receiving device which can improve the perfor mance of error correction. SOLUTION: A signal-receiving device 100 is provided with the interference cancelers of multiple stages in a demodulator 120 and a line quality exponent detector 130. The interference canceler of the first stage generates the replica of an interference signal included in a direct diffusion signal based on initial reception data, which are previously obtained from the direct diffusion signal and outputs reception data, where the influence of the interference signal is reduced based on a signal obtained, by deducting the replica from the direct diffusion signal. The interference cancelers of two and subsequent stages generate the replica of the interference signal, included in the direct diffusion signal based on reception data outputted from the interference canceler of the previous stage and outputs reception data, where the influence of the interference signal is reduced, based on the signal obtained by deducting the replica from the direct diffusion signal. A line quality exponent detector 130 compares respective pieces of reception data outputted from the respective stages of the canceler and detects the degree of matching of these reception data. |
