Abstract

　雑音量情報記憶部１６１には、予め定められた可変利得増幅部１２１，１２５の利得の値とダウンコンバータ１３１，１３５から出力されるＢＢ信号に含まれる雑音の雑音量との関係を示した雑音量情報が記憶されている。ＡＧＣ部１４０は、ダウンコンバータ１３１，１３５から出力されるＢＢ信号の電力が一定になるように可変利得増幅部１２１，１２５の利得の値を制御する。雑音量推定部１６２は、雑音量情報記憶部１６１に記憶されている雑音量情報を参照して、可変利得増幅部１２１，１２５の制御された利得の値に対応した雑音量の推定を行う。ウェイト生成部１７０は、伝送路特性推定部１５０による伝送路特性の推定結果と雑音量推定部１６２の雑音量の推定結果とに基づいてウェイト行列を生成する。
