Abstract

　空間多重ＭＩＭＯシステムにおいて、受信装置側でソフト値を用いた反復検波を行う場合に、受信品質を向上させることができるマルチアンテナ送信装置。送信装置（１６００）は、Ｍ（Ｍは２以上の整数）系統の符号化データをそれぞれ、インターリーブし、マッピングして送信するＭ個の送信部（１６０１＿１～１６０１＿Ｍ）を有する。Ｍ個の送信部（１６０１＿１～１６０１＿Ｍ）は、それぞれ、同一の送信データから得られた符号化データをそれぞれ異なるインターリーブパターンでインターリーブするＮ（Ｎは２以上の整数）個のインターリーバ（５０４Ａ１～５０４ＡＮ（５０４Ｘ１～５０４ＸＮ））と、各インターリーバによって得られた信号を送信するＮ個のアンテナ（５１０Ａ１～５１０ＡＮ（５１０Ｘ１～５１０ＸＮ））と、を有する。
