<p>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, which device comprises converting means adapted to convert said source words into corresponding m-bit channel words. The converting means are further adapted to convert a block of p consecutive n-bit source words into corresponding m-bit channel words, such that the conversion for each n-bit source word is parity inverting. 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.</p> |
