ABSTRACT:
In order to decode the bits of a message transmitted by an array of channels in parallel which have low reliability on account of the many disturbances which interfere with transmission, the binary decoding device comprises means for calculating the probability of error in each channel as a function of the coefficients of logarithmic likelihood of the decoded values and of the binary values received, as well as means for weighting the binary values received on each channel as a function of the calculated probability of error. In accordance with an optimum decision rule applied to the weighted values, a weighted decoding device delivers the binary values which are transmitted with the largest likelihood and the coefficients of logarithmic likelihood of these values.
