A succession of digital input blocks is received, each comprising two words representing the input data using a code word and a confidence word. A parametric correspondence law is determined for a parameter, and the confidence work is determined for each value of the parameter, enabling determination of a bit error rate. Application of parametric decoding law enables optimum accuracy in decoding.- DETAILED DESCRIPTION - The procedure provides decoding of a radio frequency transmission channel carrying coded digital information by modulation of a carrier in quadrature. A succession of digital input blocks is received, each comprising two words (I,Q) representing the input data using a code word and a confidence word. A parametric correspondence law is determined for at least one parameter, and the confidence word (CF2) is determined for each value of the parameter, enabling determination of a bit error rate (TEB). The value yielding the lowest bit error rate is determined for the subsequent decoding of the channel
