Abstract
The present invention relates to a method of source decoding variable-length codeword sequences, said decoding being based on an associated state diagram comprising a plurality of states (S) and on a code (C). It is characterized in that it comprises a step of reducing the states (S) in the state diagram in such a way that, at a bit time (Bj), only a number N of states in a group (G) of states is saved on the basis of a criterion derived from a partial metric computation and otherwise independently of an alphabet of said code (C), a group (G) being associated with a bit time (Bj). A group (G) corresponds to all the states (S) calculated at each bit time (Bj).
