Abstract

　ＣＣＦＩエラーが生じた場合であっても、バッファへのデータ格納ミスによる初回受信時のパケット誤りを防ぎ、再送時にずれた状態で合成することを回避する。 　送信Circular Bufferでは、送信する符号語データを末尾から先頭まで逆方向に順にＤ＿１２、Ｄ＿１１、…、Ｄ＿１と読み出し、変調部にて変調した後、多重部では、ＣＣＦＩ値（＝２）に基づき、制御チャネルＣＣＨの後に３番目のＯＦＤＭシンボル＃３から順に、変調されたデータシンボルＤ＿１２～Ｄ＿１を配置する。受信側では、受信したデータシンボルを復調した後、受信Circular Bufferにおいて、所定のデータ開始地点から、復調情報の末尾から先頭までを逆方向に並び替えて格納する。これにより、受信Circular Bufferでのデータ格納ずれや先頭のデータ欠落による受信誤りが回避される。
