Abstract:
1. A receiver comprising: a demodulator that demodulates a modulation wave modulated according to orthogonal frequency division multiplexing (OFDM), the demodulator including: an interference wave detector that detects that a received modulation wave which is received by the receiver includes an interference wave when received power of each sample of the received modulation wave exceeds a threshold, and upon the detection, executes replacement processing of replacing a received signal exceeding the threshold with a predetermined value; a first interference wave power estimation unit configured to estimate interference wave power included in an OFDM symbol included in the received modulation wave on the basis of the number of samples that have been subjected to the replacement processing in the OFDM symbol; and a demodulated data generator that demodulates the received modulation wave by executing demodulation processing of demodulating the received modulation wave that has been subjected to the replacement processing by the interference wave detector on the basis of the interference wave power estimated by the first interference wave power estimation unit, to generate demodulation data.
