Abstract

　送信装置は、複数の送信アンテナと、何れかの送信アンテナに関連付けられる送信ストリーム１つ以上から、所定の周波数帯域幅に合わせて複数の信号系列を用意する変換手段と、複数の信号系列各々を、所定のプリコーディングベクトルを複数個含むコードブックから選択されたプリコーディングベクトルで重み付けするプリコーディング手段と、プリコーディング手段からの出力信号を送信アンテナ数分の信号に変換し、変換後の信号を各送信アンテナから送信する手段とを有する。プリコーディング手段では、互いに異なるプリコーディングベクトルが、異なる信号系列に適用され、異なるプリコーディングベクトル及び異なる信号系列の対応関係は、受信装置からのフィードバックによらない開ループ制御で決定される。
