ABSTRACT:
Antennas transmit signals weighted by a weight vector. A control unit acquires, via a radio unit and the like, a predetermined column from a steering matrix derived by performing singular value decomposition on a channel matrix whose element values are channel characteristics between a plurality of transmitting antennas and a plurality of receiving antennas, respectively. The control unit varies each of components contained in the acquired column vector so as to derive a weight vector that varies with time.
