Title:
変換がパリティ反転であるようなnビット・ソースワードから対応するmビット・チャネルワードへのエンコーディング及びその逆を行うデコーディング
Document Type and Number:
Japanese Patent JP4489973
Kind Code:
B2
Abstract:
A device is disclosed for encoding a stream of databits of a binary source signal (S) into a stream of databits of a binary channel signal (C), wherein the bitstream of the source signal is divided into n-bit source words (x1, x2), which device comprises converting means (CM) adapted to convert said source words into corresponding m-bit channel words (y1, y2, y3). The converting means (CM) are further adapted to convert n-bit source words into corresponding m-bit channel words, such that the conversion for each n-bit source word is parity inverting (table I) (FIG. 1). The relations hold that m>n>=1, p>=1, and that p is an odd integer that can vary. Preferably, m=n+1. Further, a decoding device is disclosed for decoding the channel signal obtained by means of the encoding device.(FIG. 5).
