Abstract:
1. A reception device comprising: a plurality of signal receiving units for generating a plurality of received signals from a plurality of signals obtained by receiving a transmitted signal at a plurality of antennas; a plurality of signal processing units for performing processes of generating received frequency domain signals by transforming the received signals to signals in the frequency domain, calculating channel impulse responses of the received signals, calculating estimated received signals from the channel impulse responses, and calculating residual error weights with values that decrease with increasing differences between the received signals and the estimated received signals; a combining ratio calculation unit for calculating combining ratios for the received frequency domain signals such that the ratios decrease as the residual error weights decrease; a diversity combining unit for combining the received frequency domain signals according to the combining ratios to generate a diversity combined signal; and an inverse transform unit for transforming the diversity combined signal to a time domain signal.
