Abstract
【解決手段】 データチャネル33に対して複数のサブキャリア31を割り当て、制御チャネル34に対して前記複数のサブキャリア31よりも少ないサブキャリア32を割り当てるとともに、前記データチャネル33の送信に使用する周波数帯域の中心周波数fCに前記制御チャネル34を割り当てることにより、無線受信装置側において、受信信号に対して乗算されるローカル信号の周波数を共通化し、制御チャネル及びデータチャネル間の切り換えを高速化することができる。
【選択図】 図2
Description
図1は、本発明の実施の形態1に係る無線送信装置10の構成を示すブロック図である。
図5は、本発明の実施の形態2に係る無線送信装置60の構成を示すブロック図である。
上述の実施の形態においては、図2に示したようにデータチャネル33と制御チャネル34とを近接させて配置した場合について述べたが、本発明はこれに限らず、図8に示すように、例えばIFFT部16(図1)を制御することによって、制御チャネル34とデータチャネル33との間にガード周波数帯111、112を設けるようにしてもよい。このようにすれば、バンドパスフィルタ44(図3)の通過帯域幅を広くすることができ、この分、フィルタ構成の回路規模を小さくすることができる。
