Abstract

 バーチャルアンテナを用いる際にも複数のアンテナポートの伝搬路の分離を可能にしてチャネル推定精度を向上させることができる無線通信装置。この装置において、マッピング部(103)は、変調後のデータ信号をバーチャルアンテナ0およびバーチャルアンテナ1にそれぞれマッピングし、奇数スロットと偶数スロットとの間で、位相反転部(104)は位相反転部(105)と同期して、アンテナポート2から送信されるS0の位相を反転させ、位相反転部(105)はアンテナポート2から送信されるR0の位相を反転させ、位相反転部(113)は位相反転部(114)と同期して、アンテナポート3から送信されるS1の位相を反転させ、位相反転部(114)は、アンテナポート3から送信されるR1の位相を反転させる。
