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。
11 拡散部
14,65 多重化部
16,67 IFFT部
18,43,69,94 乗算部
