Abstract

【課題】処理の遅延を低減させ、バッファリング容量および消費電力を低減させることが可能な無線信号受信装置を提供する。 【解決手段】本発明に係る無線信号受信装置２００は、受信された無線信号からサブフレーム１１を抽出し、サブフレームの先頭にあり制御チャネルを構成する第１のＯＦＤＭシンボル１２ａにデータチャネルに含まれる受信装置宛の信号３４についての情報が存在するか否かを判断し、存在すれば複数のＯＦＤＭシンボル１２ｂ～ｎを出力するデマップ部２０５と、デマップ部から出力された複数のＯＦＤＭシンボルを復号化する復号部２０８とを有し、第１のＯＦＤＭシンボルに受信装置宛の信号についての情報が存在しなければデマップ部がサブフレームの受信の処理を打ち切る。
