Abstract
A device for decoding coded digital signals for every symbol consisting of a plurality of binary signals comprises first circuit for generating a first reliability for every binary signal; hard decided from the received or reproduced signal, in the symbol and second circuit for generating a second reliability for every symbol consisting of n binary signals on the basis of the first reliability, whereby decoding processing e.g. soft decision decoding is effected for every signal, depending on the second reliability.
