Abstract
La présente invention concerne un émetteur. L'émetteur comprend : un encodeur à contrôle de parité à faible densité (LDPC) qui encode des bits d'entrée comprenant des bits à codage externe pour générer un mot de code LDPC contenant les bits d'entrée et des bits de parité devant être transmis à un récepteur dans une trame actuelle; un perforateur qui perfore une partie des bits de parité qui n'est pas transmise dans la trame actuelle; et un générateur de bits de parité supplémentaires qui sélectionne au moins une partie des bits de parité pour générer des bits de parité supplémentaires transmis au récepteur dans une trame antérieure à la trame actuelle. Un nombre des bits de parité supplémentaires est déterminé sur la base d'un nombre des bits à codage externe et d'un nombre de bits de parité restants après la perforation.
