Title (EN) HIGH RATE TURBO ENCODER AND DECODER FOR PRODUCT CODES
(FR) TURBO-CODEUR ET TURBO-DECODEUR HAUT DEBIT POUR CODES DE PRODUIT
Abstract:
(EN) The invention relates to a method of decoding a matrix built from concatenated elementary codes with uniform interleaving having nl lines, n2 columns and nl*n2 symbols, wherein the method comprises a process of all the lines- and columns-vectors of the matrix by symbols groups, this process comprises a first decoding for simultaneously processing all the symbols of a group of symbols according to their lines and then a second decoding for simultaneously processing all the symbols of the said group of symbols according to their columns while using extrinsic information produced in the line processing step, the symbols groups being thus successively processed in lines and in columns .
(FR) La présente invention a trait à un procédé de décodage d'une matrice construite à partir de codes concaténés élémentaires à entrelacement uniforme, comprenant n1 lignes, n2 colonnes et n1*n2 symboles., ledit procédé comprenant un traitement de tous les vecteurs de lignes et de colonnes de la matrice par des groupes de symboles, ce traitement comprenant un premier décodage pour le traitement simultané de tous les symboles d'un groupe de symboles selon leurs lignes et ensuite un deuxième décodage pour le traitement simultané de tous les symboles dudit groupe de symboles selon leurs colonnes en utilisant une information extrinsèque produite dans l'étape de traitement de lignes, les groupes de symboles étant ainsi traités successivement en lignes et en colonnes.
