Abstract
A coherent bandwidth calculation unit () calculates a coherent bandwidth based on a channel response in the time domain obtained from reception signals (R-R) for each path between transmitting antennas and receiving antennas. A weight calculation control unit () determines target subcarriers of equalization weight calculation based on the coherent bandwidth. A weight calculation unit () calculates the equalization weight of each target subcarrier. A weight interpolation unit () performs interpolation processing using the equalization weights so as to obtain equalization weights for the subcarriers that have not undergone equalization weight calculation yet.
