Abstract
A reception device includes signal receiving units that generate received signals from signals obtained by receiving a transmitted signal at antennas, signal processing units that perform 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 that calculates combining ratios for the received frequency domain signals such that the ratios decrease as the residual error weights decrease, a diversity combining unit that combines the received frequency domain signals according to the combining ratios to generate a diversity combined signal, and an inverse Fourier transform unit that transforms the diversity combined signal to a time domain signal.
