A transmitting apparatus (1) forms a plurality of transmission beams 1~M by using a plurality of antennas (15-1ˆ¼15-4). Transmission beams 2 and 3, the correlation of which is low and the reception quality of which is high, are selected. A data stream 1 is transmitted by using the transmission beam 2, and a data stream 2 is transmitted by using the transmission beam 3. As a result, a MIMO multiplexing transmission using an adaptive array antenna is implemented.
