Abstract

　ＳＣＨ用送信ダイバーシチ方法としてＰＶＳを適用することができ、サイドローブを回避して隣接セルサーチ性能を改善することができる基地局装置、移動局装置、通信システム、チャネル推定方法、送信アンテナ検出方法及びプログラム。これらにおいて、ＳＣＨの周波数軸上にＰＶＳを適用する際に、サブキャリアグループ間に異なるプリコーディングウェイトを適用し、複数のＰＳＣ系列とプリコーディングウェイト行列を対応させ、ＰＳＣ系列を特定する。また、サブキャリアグループに割り当てるサブキャリア数と送信アンテナ数を対応させ、受信ＳＣＨ信号の自己相関特性の周期性を検出することで送信アンテナ数を特定する。
