Abstract

La présente invention se rapporte à un émetteur. L'émetteur comprend : un codeur à contrôle de parité et faible densité (LDPC) configuré afin de coder des bits à codage externe en vue de générer un mot de code LDPC comprenant des bits d'information LDPC et des bits de parité ; un perforateur conçu pour perforer certains des bits de parité inclus dans le mot de code LDPC ; et un mappeur configuré pour mapper le mot de code LDPC à l'exception des bits de parité perforés à des symboles en vue d'une transmission à un récepteur, lequel perforateur calcule un certain nombre de bits de parité devant être perforés parmi les bits de parité inclus dans le mot de code LDPC sur la base d'un certain nombre de bits à codage externe, un certain nombre de bits d'information LDPC, et un nombre minimum de bits de parité devant être perforés parmi les bits de parité inclus dans le mot de code LDPC.
