Abstract

La présente invention concerne un système, un procédé et un produit de programme informatique permettant l'atténuation de bruit impulsif sur des paquets transmis dans un système de communications. Un dispositif de transmission applique un code externe, qui peut comprendre, par exemple, un code bloc, un code porte OU exclusif (XOR), ou un code de répétition, à un ou des paquets préalablement à l'adaptation des paquets pour la transmission sur la couche physique (PHY) du système de communications, dans lequel la couche d'adaptation PHY peut comprendre un codage de correction aval des erreurs (FEC) des paquets individuels. Les paquets à code externe sont ensuite transmis séparément sur le canal du système de communications. Un dispositif de réception reçoit les paquets à code externe, effectue une démodulation du niveau de la couche d'adaptation PHY et un décodage facultatif de correction aval des erreurs (FEC), et applique un décodage de code externe aux paquets à code externe afin de reconstituer les paquets qui ont été effacés en cours de transmission dû au bruit impulsif ou autre altérations sur le canal.
