Abstract[English]
Methods and processors for executing Forward Error Correction (FEC) coding are provided. The method includes acquiring a stream of real data symbols from a communication medium. The stream of real data symbols being arranged in a real matrix. The method includes generating virtual data symbols being arranged in a virtual matrix. The generating includes applying an interleaver map onto the matrix such that at most c number of virtual data symbols in a given virtual row of the virtual matrix are copies of real data symbols associated with a same real row of the real matrix, c being a positive integer higher than 1. The method includes decoding codewords formed by the virtual matrix and the real matrix.[French]
L'invention concerne des procédés et des processeurs permettant d'exécuter un codage de correction d'erreurs sans circuit de retour (FEC). Le procédé consiste à acquérir un flux de symboles de données réels à partir d'un support de communication. Le flux de symboles de données réels est disposé dans une matrice réelle. Le procédé consiste à générer des symboles de données virtuels qui sont disposés dans une matrice virtuelle. La génération consiste à appliquer une carte d'entrelaceur sur la matrice de telle sorte qu'au plus c nombres de symboles de données virtuels dans une rangée virtuelle donnée de la matrice virtuelle sont des copies de symboles de données réels associés à une même rangée réelle de la matrice réelle, c étant un nombre entier positif supérieur à 1. Le procédé comprend le décodage de mots de code formés par la matrice virtuelle et la matrice réelle.
