Abstract
A device 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 (x.sub.1, x.sub.2), which device includes a converting circuit (CM) adapted to convert the source words into corresponding m-bit channel words (y.sub.1, y.sub.2, y.sub.3). The converting circuit (CM) is further adapted to convert n-bit source words into corresponding m-bit words, such that the conversion for each n-bit source word is parity preserving (table I). The relations hold that m>n.gtoreq.1, p.gtoreq.1, and that p can vary. Preferably, m=n+1. Further, a decoding device is disclosed for decoding the channel signal obtained by means of the encoding device.
