Abstract

　高伝送レート時の誤り率特性の確保と、セルカバレッジの拡大といった要求に、柔軟に対応できる無線送信装置（１００）。無線送信装置（１００）は、複数の変調信号が周波数領域に変換された第１のサブキャリア変調信号を形成する第１のサブキャリア変調部（１０４）と、複数の変調信号がパラレル変換された第２のサブキャリア変調信号を形成する第２のサブキャリア変調部（１０５）と、第１及び第２のサブキャリア変調信号を逆フーリエ変換することで、ＯＦＤＭ信号を形成するＩＦＦＴ部（１１１）と、ＯＦＤＭ信号を構成する複数サブキャリアへの、第１及び第２のサブキャリア変調信号の割り当てを制御するサブキャリアマッピング部（１１０）とを有する。
