Abstract

　ＦＤＥにプリコーディングを併用する移動体通信において、データレートを低下させることなく誤り率特性の劣化を防ぐことができる無線送信装置。この装置において、変調部（１０２）は、送信データのうちの第１データを第１変調方式で変調して第１シンボル列を生成し、変調部（１０３）は、第１変調方式の変調多値数より大きい変調多値数の第２変調方式で、送信データのうちの第２データを変調して第２シンボル列を生成し、複製部（１０４）は、第２シンボル列を複製して複数の第２シンボル列を得る。そして、配置部（１０５）は、第１シンボル列の両側に複数の第２シンボル列をそれぞれ配置し、プリコーディング部（１０６）は配置後の各シンボル列に対してプリコーディングを行う。
