Abstract

シングルキャリア信号を複数の受信アンテナで受信し、周波数領域においてマルチパス等化と他セル干渉抑圧を同時に行う受信装置を提供する。受信アンテナ１－１～Ｎは、シングルキャリア信号を受信する。ＤＦＴ部３－１～Ｎは、受信信号を周波数領域の信号へ変換する。チャネル推定部５は、パイロット受信信号を用いて所望のユーザ信号のチャネル利得を推定する。干渉相関行列推定部６は、パイロット受信信号とチャネル推定値から干渉相関行列を推定する。ウエイト計算部７は、チャネル推定値と干渉相関行列を入力され、等化ウエイトを計算する。等化部８は、周波数領域において所望のユーザ信号のマルチパス等化と他セル干渉抑圧を行う。ＩＤＦＴ部９は、等化信号を時間領域の信号へ変換する。
