Summary:The method according to the invention relates to the decoding of a sequence of symbols, the sequence of symbols having been generated by: calculating a CRC value for an initial message; combining the initial message and the CRC value so as to produce a transformed message; and, encoding the transformed message. The decoding comprises: generating a number of path hypotheses via a trellis diagram corresponding to the trellis diagram of a finite-state machine comprising the encoder and the CRC generator, in which the encoder and the CRC generator are supplied with the same input. According to a preferred embodiment of the method, the trellis diagram is adapted to take into account bit stuffing possibly inserted in the transformed message before encoding.
