Abstract

　本発明は、ＯＦＤＭ信号の受信装置において、離散フーリエ変換後のキャリア間干渉による受信性能の劣化を軽減することを目的とする。周波数変換部（１）は受信信号を所望の周波数に周波数変換する。時間軸データ拡張部（２）は、周波数変換部（１）の出力から少なくともガードインターバルを含めた１シンボル分に相当するＫ＋Ｎ個のデータを抽出し、その前後に０を付加することで２Ｎ個のデータを生成する。窓整形部（３）は時間軸データ拡張部２の出力に窓係数を乗算して波形整形し、離散フーリエ変換部（４）は窓整形部（３）の出力に対して離散フーリエ変換を行う。復調部（５）はサブキャリア成分を抽出してサブキャリアの復調を行う。キャリア間干渉成分算出部（６）は離散フーリエ変換部（４）の出力よりキャリア間干渉成分を算出する。窓係数生成部（７）は、キャリア間干渉成分算出部（６）の出力に基づき窓係数を選択して、窓整形部（３）に出力する。
