Abstract

Selon certains modes de réalisation, un procédé destiné à être utilisé dans un émetteur sans fil d'un réseau de communication sans fil consiste à coder des bits d'informations à l'aide d'une matrice de contrôle de parité (pcm) et à transmettre les bits d'informations codés à un récepteur sans fil. La matrice de contrôle de parité (pcm) est optimisée conformément à au moins deux contraintes de degré de message extrinsèque de cycle approximatif (ace). Selon certains modes de réalisation, une première partie de la pcm est optimisée conformément à une première contrainte ace et une seconde partie de la pcm est optimisée conformément à une seconde contrainte ace.
