Abstract

複数の第１の無線通信装置は、送信信号を、周波数拡散して周波数拡散信号を生成する周波数拡散部と、周波数拡散信号を、サブキャリアを指定するマッピング情報に従いサブキャリアに割り当てるマッピング部とを具備し、第２の無線通信装置は、受信した信号から、マッピング情報にて指定されたサブキャリアの信号を抽出するデマッピング部と、抽出した信号を、逆周波数拡散する逆周波数拡散部とを具備し、第１の無線通信装置が送信に用いるアンテナ毎の各サブキャリアの通信路容量に基づき、周波数拡散信号を割り当てるサブキャリアを決定し、該決定したサブキャリアを指定するマッピング情報を生成する使用サブキャリア決定部を、第１の無線通信装置、または、第２の無線通信装置のいずれかが具備することを特徴とする無線通信システム。
