<p>An adaptive antenna transmission apparatus, used in a base station apparatus of a cellular communication system, for transmitting signals via a plurality of antenna elements constituting an adaptive antenna. In the adaptive antenna transmission apparatus of a base station apparatus (1), an interference processing part (7) detects an interference wave component, which is a reflected component of a downstream signal transmitted to the base station (1), and a signal processing part (4) controls, in accordance with the detection result, the downstream transmission directivity so as to minimize the reflected component. This can reduce the interference electric power of the downstream-transmitted signal in the base station apparatus (1), thereby preventing degradation of the line capacity and allowing the base station to be operated in an effective manner.</p> |
