Abstract

　受信処理のために用意されている信号列であって第２変調方式で用いられる信号列から生成可能な第１変調方式での受信処理に用いられる信号系列を採用することで、第２変調方式での受信処理パフォーマンスと同程度のパフォーマンスを実現できる、無線通信方法、無線送信装置、及び、無線受信装置。無線送信装置（２０）が、第２の変調方式（例えば、ＢＰＳＫ変調方式）用に設計されている第２のシーケンスａ（ｎ）と同一のサブシーケンスａ１（ｎ）、および第２のシーケンスａ（ｎ）とビットが反転しているサブシーケンスａ２（ｎ）を時分割で連続して第１の変調方式（例えば、ＯＯＫ変調方式）により第１のシーケンスとして送信し、無線受信装置（３０）が、受信信号の中からサブシーケンスａ１（ｎ）およびサブシーケンスａ２（ｎ）を検出し、検出結果を信号処理のために後段の処理に渡す。
