Abstract

　ＺＣ系列間の相互相関ピークの発生を防止し、ＣＳ－ＺＣ系列のＢＬＥＲ特性の劣化を低減することができる無線通信装置。この装置において、系列長調整部（１０３）は、ＺＣ系列生成部（１０２）から入力されるＺＣ系列の対称性を維持したままＺＣ系列をトランケーションまたはエクステンションして、系列長を系列長設定部（１０１）から入力される参照信号の送信帯域幅に相当するサブキャリア数に調整する。具体的には、系列長調整部（１０３）は、ＺＣ系列を構成する複数のシンボルのいずれかをトランケーションまたはエクステンションすることによりＺＣ系列をトランケーションまたはエクステンションする。そして、送信ＲＦ部（１０７）は、系列長調整後のＺＣ系列を送信する。
