Claim One:
1. A binary decoding device for decoding bits of a message, said bits being received from a group of n channels C.sub.i (n being a positive whole number, i being a whole number which varies from 1 to n, each binary data of said message being either transmitted simultaneously on each of the n channels, or transmitted in a linear code), comprising means for weighting the values of the bits received having n inputs E.sub.i coupled respectively to the n channels C.sub.i, n inputs e.sub.i and n outputs S.sub.i ; a device for weighted decoding of each of the bits received having n inputs coupled respectively to the n outputs S.sub.i of the weighting means and m outputs r.sub.j (m being a positive whole number, j being a whole number which varies from 1 to m) for delivering respectively m relative quantities A.sub.jt at the instant t, the sign and the modulus of each quantity A.sub.jt being such as to represent respectively a binary value which has been transmitted with the highest probability and the coefficient of logarithmic likelihood of said value; means for calculating the probability of error in the case of each of the channels C.sub.i by comparing each of the bits received with the result of its decoding, said calculating means being provided with n inputs coupled respectively to the n channels C.sub.i, m additional inputs coupled respectively to the m outputs r.sub.j of the weighted decoding device, and n outputs V.sub.i coupled respectively to the n inputs e.sub.i of the weighting means, said n outputs being intended to deliver the probability error p.sub.i of each channel.
