【課題】複数帯域同時伝送を用いる通信システムにおいて、帯域ごとに変調方式が異なり、異なる伝搬環境となる場合にも、フレームエラーレートを予測する技術を提供する。【解決手段】畳み込み符号化直交周波数分割多重方式により、複数の周波数帯による同時伝送で通信する通信システムのフレームエラーレート予測装置１１１０は、畳み込み符号化処理手段の構成により定まるエラーパターンの誤りビットがマッピングされる周波数帯域と、誤りビットがマッピングされるサブキャリアとビット位置とをインターリーバーおよびパーサーの構成から決定し、各周波数帯域の受信パワー、伝搬路特性情報および雑音電力の推定値からペアワイズ誤り率を計算し、フレーム誤り率を予測するフレーム誤り率予測部３０３０とを備える。【選択図】図５ |
