Abstract:
A reception device which receives a signal transmitted by a transmission device which changes at least one of a modulation scheme and a coding rate. The reception device includes an equalization unit which equalizes a received signal in frequency domain, a reliability calculation unit which calculates the reliability of a transmitted bit from the received signal after equalization, a mutual information amount calculation unit which calculates a mutual information amount based on the reliability of the transmitted bit calculated by the reliability calculation unit, and a notification signal generation unit which sets at least one of a modulation scheme and a coding rate based on the mutual information amount calculated by the mutual information amount calculation unit to generate a signal to be reported to the transmission device.
