Receiver and its receiving method

摘要

In prior art, when plural frequency selective interferences having different degrees of influences occur, there is a possibility that interference may be unfavorably undetected. An average power indicating channel characteristics is outputted from a reference value calculation unit (7) as a reference value. An interference level corresponding to the degree of influence by frequency selective interference is outputted from an interference detection unit (8). A reliability determination unit (9) determines a carrier that has been subjected to interference on the basis of the reference value and the interference level, to decide a reliability level. An error correction unit (6) performs error correction of a demodulation signal on the basis of the reliability level.
