An adaptive antenna transmission apparatus, used in a base station apparatus of a cellular communication system, for transmitting signals by a plurality of antenna elements constituting an adaptive antenna. In the adaptive antenna transmission apparatus, a base station apparatus (1) detects an interference component, which is a reflection component of a downlink transmission signal of its own base at an interference processing part (7), and controls the downlink transmission directivity, in accordance with the result of detection at a signal processing part (4) , so as to minimize the reflected component. This can reduce the interference power of the downlink transmission signal at the base station apparatus (1) , and thereby can prevent decrease of the channel capacity and make the effective operation of the base station. <IMAGE> |
