Abstract

La présente invention concerne un procédé et un système d'entrelacement de blocs d'un paquet qui permet de réduire au minimum les effets dus à des paquets d'erreurs, et en même temps d'améliorer l'efficacité du protocole ARQ. Un paquet est d'abord divisé en plusieurs blocs. Chaque bloc est ensuite codé individuellement et entrelacé de façon interne. Après quoi les blocs sont entrelacés sur une plus longue période temporelle. Par la mise en oeuvre de deux étapes d'entrelacement, la présente invention permet de maintenir au minimum la taille d'un bloc de paquets, ce qui accroît l'efficacité du protocole ARQ et permet d'obtenir un plus grand entrelacement des éléments de données de paquet de façon à réduire au minimum les effets dus à des paquets d'erreurs.
