Description
本稿では, 畳み込み符号を内符号に, Reed-Solomon符号を外符号とする一般化連接畳み込み符号のフレーム復号誤り率の上界を導出する.内符号と外符号の間にランダムインターリーバを入れることにより平均重み母関数によるビット誤り率解析が可能となることを示し, それを利用することでフレーム復号誤り率の上界を導く.ここで提案される上界により, 外符号の構成(冗長の配分)を最適化することが可能となった.
An upper bound on frame error rate(FER)for generalized concatenated convolutional codes(GCCC's)with iterative decoding is presented. The GCCC is a generalized concatenated code which consists of an inner binary convolutional code and outer Reed-Solomon codes. The FER bound is derived from the average weight enumerator of the inner code.
