Abstract

　重要度の高いビット等といった所定のビットの受信信頼度を向上させることができる無線通信装置、無線通信方法および無線通信システムを提供する。指定された変調方式、符号化率とＳ２のビット長から、符号長Ｌが決定する。中継局は、符号長Ｌから、Ｓ１の符号化率を決定する。１６ＱＡＭの場合、象限判定となるビットは全体のビットの１／２であるので、Ｓ１の符号長をＬ／２とする。したがって、Ｓ１の符号化率は、Ｓ１のビット長をＬＳ１とすると２（ＬＳ１）／Ｌとなる。本例では、Ｓ１は符号化されＳ１＋Ｐ１となり、Ｓ２はＳ２＋Ｐ４となっている。Ｐ１は、Ｓ１のパリティビット、Ｐ４はＳ２のパリティビットを示す。中継局は、Ｓ１の符号語（Ｓ１＋Ｐ１）の各ビットがすべて１６ＱＡＭのコンスタレーションの象限判定の位置にくるようにビット配置を変更する。
