MIMO RECEPTION DEVICE AND METHOD

摘要

A coherent bandwidth calculation unit (41) calculates a coherent bandwidth based on a channel response in the time domain obtained from reception signals (R 1 - R N ) for each path between transmitting antennas and receiving antennas. A weight calculation control unit (42) determines target subcarriers of equalization weight calculation based on the coherent bandwidth. A weight calculation unit (31) calculates the equalization weight of each target subcarrier. A weight interpolation unit (43) performs interpolation processing using the equalization weights so as to obtain equalization weights for the subcarriers that have not undergone equalization weight calculation yet.
