Abstract

　並列干渉キャンセラの処理遅延を短縮する受信装置。受信装置(200)は、複数の受信アンテナ(210A、210B)と、あらかじめ定められた並び替え規則に従って、チャネル推定値の書き込みまたは読み出しの順番を変換するアドレス発生部(2332)と、変換した順番にチャネル推定値を書き込むチャネル推定記憶部(2334)と、並び替え規則に従って、データ系列の書き込みまたは読み出しの順番を変換するアドレス発生部(2338)と、変換した順番にデータ系列を書き込みまたは読み出す信号記憶部(2340)と、チャネル推定値に基づき、データ系列を再変調してレプリカ信号を生成するレプリカ生成部(2336)と、チャネル推定値とデータ系列とを順番に取り出し、チャネル推定値、データ系列およびレプリカ信号を用いて、データ系列の干渉信号をキャンセルしたストリーム信号を生成するキャンセル部(2342)と、ストリーム信号に基づき、誤り訂正復号を行う誤り訂正復号部(2350)とを含む。
