ABSTRACT:
Data blocks to be received each comprise a header and a data field including respectively first and second codes for error detection. The decoding of a signal segment received having first and second portions corresponding respectively to the header and to the data field of a block gave rise to a verification of the first code in the first portion. If the first code is correct, a check is made to verify whether the second portion of the decoded signal has a second correct code. A data block is considered to be detected either in the presence of first and second correct codes, or in the presence only of a first correct code when a data likelihood criterion, evaluated during the decoding of the second portion of the signal, is fulfilled.
