Abstract

　ＬＤＰＣ－ＣＣ（Low-Density Parity-Check Convolutional Codes：低密度パリティ検査畳み込み符号）符号化・復号化に必要なターミネーション系列の量を削減し、伝送効率の劣化を抑圧しつつ、誤り訂正符号化・復号化を行うＬＤＰＣ－ＣＣ符号化器及びＬＤＰＣ－ＣＣ復号器。ＬＤＰＣ－ＣＣ符号化器（４００）において、ウェイト制御部（４７０）は、ＬＤＰＣ－ＣＣ検査行列（１００）に準じたウェイトパターン（４７５）と、ＬＤＰＣ－ＣＣ検査行列（１００）を変形した検査行列（３００）に準じたウェイトパターン（４７６）と、を記憶し、入力ビットが情報系列の場合に、ウェイトパターン（４７５）を用い、入力ビットがターミネーション系列の場合に、検査ビットｖ2,ｔと乗算されるウェイト値を０にするウェイトパターン（４７６）を用いて、複数のシフトレジスタ（４１０－１～４１０－Ｍ，４３０－１～４３０－Ｍ）の出力に乗算するウェイトを制御する。
