Abstract

　シンセサイザ２１から出力される直交復調器１４－１、１４－２に与えるローカル搬送波に、サブキャリアの帯域幅を単位として、サブキャリアの整数個分を周波数シフトするオフセットを乗算する。オフセットは、信号帯域のガードトーンに含まれる未使用のサブキャリアの数だけ０から順番に計数した値にサブキャリアの帯域幅を乗算した値とする。直交復調する際のローカル搬送波の周波数をオフセットでシフトすることにより、受信機の回路が有する周波数特性によってベースバンド信号のSNRの劣化が特定のサブキャリアの信号に恒常的に起きるのを防ぐ。特に、Pilot信号の劣化が恒常的におきることを防ぐことにより、信号の受信をより精度良く行うことが出来る。
