Abstract

L'invention concerne un procédé et un système de codage et de correction d'erreurs faisant intervenir un codeur-décodeur AMR (18) par tri de données d'en-tête dans une pluralité de trames de systèmes existants (10) comportant des blocs de données d'en-tête et de canal de trafic. Des données de parole sont ensuite codées au moyen du codeur-décodeur AMR afin de créer des bits pour un bloc de données essentiellement égal à celui contenu dans la pluralité de trames. Les données d'en-tête triées sont codées en tant qu'en-tête de trame longue au moyen d'un codeur convolutif fixe (24). Les données de parole sont ensuite codées de façon convolutive et l'en-tête de trame longue et des données de parole codées sont combinés en tant que trame longue (32). La trame longue est ensuite séparée en une pluralité de segments égaux (106, 110) et les segments sont transmis en tant que données TCH dans le format de trame du système existant.
