Base station device

Abstract

A base station apparatus according to the present invention is provided with antenna elements for a plurality of branches arranged so as to have a mutually vertical positional relationship at a sequence-specific predetermined position in the horizontal plane on a sequence-by-sequence basis, a signal processing section that generates a weight specific to each above-mentioned sequence by performing adaptive array antenna processing using a signal received by an antenna element for each sequence on a branch-by-branch basis, and generates a combined signal that combines signals resulting from multiplying a signal transmitted by an antenna element for each above-mentioned sequence by a sequence-specific weight, and a diversity combining section that generates a received signal by performing diversity combining using combined signals for each branch. By this means, it is possible to suppress the effects of fading and interference and obtain a received signal with good characteristics while maintaining good communication quality in a mobile station apparatus.
