Abstract

　ネットワークコーディングデータ伝送時の受信性能を上げ、システムの伝送遅延を低減することができる無線送信装置および無線送信方法を提供する。復号化部１８は復調信号に対して、誤り訂正復号化を実施し、バッファ１７へ出力する。バッファ１７は、一定時間、データパケットを保存し、符号化部１２へ出力する。符号化制御部１１は、送信データに対する符号化率を制御し、制御情報を符号化部１２へ出力する。符号化部１２は、符号化制御部１１からの制御情報に基づいて、データパケットに対して、誤り訂正符号化を実施し、コーディング部１３へ出力する。コーディング部１３は、対となるデータ系列に対して、ＸＯＲ処理を行い、変調部１４へ出力する。無線送信部１５は、変調信号に、Ｄ／Ａ変換、アップコンバート、増幅等の送信処理を施し、送信処理を施した信号をアンテナ１６から無線送信する。
