Abstract

　通信相手に対して変調情報を効率よく通知する。伝搬路情報および変調情報から定められるビットマップ情報に基づいて、サブキャリア毎またはグループ化されたサブキャリア群毎に第１の変調情報を決定する第１の変調情報決定部１と、第１の変調情報を、異なるデータ空間に変換するデータ変換部２と、変換されたデータを圧縮し、通信相手に通知する第２の変調情報を決定する第２の変調情報決定部３と、第２の変調情報を元のデータ空間に逆変換する逆データ変換部４と、逆変換されたデータとビットマップ情報とに基づいて、サブキャリア毎またはグループ化されたサブキャリア群毎に第３の変調情報を決定する第３の変調情報決定部５と、を有する。
