Abstract:
1. Method for determining a copy to be decoded and an associated erasures vector by means of a receiver device receiving at least two copies of a same piece of data encoded according to an error correction code, each received copy comprising several symbols, each associated with a position index in said copy, said copy to be decoded being designed to be decoded in taking account of the erasures vector by means of a decoder of a first type applying a decoding adapted to the error correction code, said method wherein it comprises steps for: obtaining, for at least one symbol of each copy received, a level of reliability of transmission associated with said symbol; marking or not marking, for at least one given position index associated with a symbol included in said copy to be decoded, an erasure for said given position index in said erasures vector as a function of the reliability levels associated with the symbols which are positioned at said given position index in said received copies.
