Title (EN) METHOD AND SYSTEM FOR ENCODING A DATA SEQUENCE
(FR) PROCEDE ET SYSTEME D'ENCODAGE D'UNE SEQUENCE DE DONNEES
Abstract:
(EN) The invention concerns a communication a method and a system comprising a first entity (3) including an information source (9) and a coding device (11), connected via a channel (7) transmitting data to a second entity (5) including a decoding device (13), the encoding device (11) being designed to encode a data sequence emitted by the information source (9) to form a set of code words from a parity check matrix comprising two matrix zones, each matrix zone including at least one processing matrix, one matrix including a single '1' per column and a single '1' per line, and a triangular matrix; and the decoding device being designed to decode an encoded reception signal received by the second entity, said encoded reception signal being derived from the set of code words constructed in accordance with said parity check matrix.
(FR) L'invention concerne un procédé et un système de communication comportant une première entité (3) comprenant une source d'information (9) et un dispositif encodeur (11), connectée via un canal (7) de transmission de données à une seconde entité (5) comportant un dispositif décodeur (13), le dispositif encodeur (11) étant destiné à encoder une séquence de données émise par la source d'information (9) pour former un ensemble de mots de code à partir d'une matrice de contrôle de parité comportant deux zones matricielles, chaque zone matricielle comprenant au moins une matrice de traitement, une matrice de liaison comportant un unique « 1 » par colonne et un unique « 1 » par ligne, et une matrice triangulaire ; et le dispositif décodeur (13) étant destiné à décoder un signal codé de réception reçu par la seconde entité, ledit signal codé de réception étant issu de l'ensemble de mots de code construit selon ladite matrice de contrôle de parité.
