Abstract

　複数のアンテナ11-1～11-Mを有し、これら複数のアンテナ11-1～11-Mの受信信号をダイバーシティ合成する無線通信装置において、複数のアンテナ11-1～11-Mの受信電力に基づいて、アンテナ合成振幅および合成重みを算出する合成情報算出部14と、算出された合成重みに基づいて、複数のアンテナ11-1～11-Mの受信信号を重み付けして合成する合成部15と、算出されたアンテナ合成振幅に基づいて、合成部15で生成された合成受信信号を復号処理する復号処理部16と、を備える。これにより、受信アンテナが少なくても、遅延到来波を伴うマルチパスフェージングの影響を低減して、復号処理のフェージング耐久性を改善し、常に安定した受信状態を維持するとともに、ハードウェアの小型化およびコストダウンを図る。
