Title:
DEVICE FOR ENCODING/DECODING N-BIT SOURCE WORDS INTO CORRESPONDING M-BIT CHANNEL WORDS, AND VICE VERSA
Document Type and Number:
WIPO Patent Application WO1999035747
Kind Code:
A3
Abstract:
A device is disclosed for encoding a stream of databits of a binary source signal into a stream of databits of a binary channel signal. The device comprises a merging unit (4') for merging a 1-bit merging word at equidistant positions in the serial datastream of the binary source signal, so as to obtain a composite binary source signal. A shuffling step is carried out on the composite binary source signal in a shuffling unit (8'). Next a conversion is carried out in a converter unit (10'), resulting in the channel signal (Fig. 2). Further, a decoding device is disclosed for decoding the channel signal obtained by means of the encoding device.
