Cette lettre propose un algorithme de décodage itératif simple pour les codes de concaténation où le code externe est un code SPC (Single-Parity-Check). Les mots de code internes erronés sont combinés de manière itérative avec une combinaison de rapport maximum (MRC), puis re-décodés. Comparé au schéma conventionnel dans lequel la concaténation du code externe RS est décodée algébriquement pour récupérer les effacements, le schéma proposé présente de meilleures performances grâce au traitement MRC. D'autre part, le schéma proposé est moins complexe car la combinaison linéaire est plus simple que le décodage algébrique et le gain MRC peut perdre l'exigence d'un décodeur interne.

Abstract: This letter proposes a simple iterative decoding algorithm for the concatenation codes where the outer code is single-parity-check (SPC) code. The erroneous inner codewords are iteratively combined with maximum ratio combining (MRC) and then re-decoded. Compared with the conventional scheme where the RS outer code concatenation is algebraically decoded to recover the erasures, the proposed scheme has better performance due to MRC processing. On the other hand, the proposed scheme is less complex because the linear combination is simpler than algebraical decoding and the MRC gain can loose the requirement for inner decoder.
