Abstract

　直交変換器１１１３－１～１１１３－ＮＲは、受信した無線信号から抽出するＮ個の時系列データに対して直交変換を行う。マルチユーザ検出器１１１４－１～１１１４－Ｎは、直交変換された時系列データから、各送信装置からの送信信号を抽出する。逆直交変換器１１１５－１～１１１５－ＮＴは、抽出された送信信号に対して逆直交変換を行い、矩形フィルタ回路１１１６－１～１１１６－ＮＴは、逆直交変換された送信信号から、先端部のＭｈ個と終端部のＭｔ個との時系列データを除去し、Ｎｗ個の時系列データを抽出する。デ・インターリーバ回路１１１９－１～１１１９－Ｕは、上記時系列データをデ・インターリーブし、復号器１１２０－１～１１２０－Ｕは、復号して出力する。
