PROBLEM TO BE SOLVED: To provide an interference canceller that generates a proper replica to decrease interference between users. SOLUTION: An error detection of a signal obtained by applying hard decision to a signal after FEC(Forward Error Correction) decoding is carried out, and when the error is detected, a replica is generated by applying a smaller weighting coefficient to the signal with the error or a replica is generated by using a tentative decision value (hard or soft decision value) before the FEC decoding. Furthermore, when the error detection result in a pre-stage denotes OK, by using a hard decision value in the pre-stage, a replica is generated. |
