Abstract

L'invention concerne un procédé de synchronisation d'un dispositif de réception de données brouillées au moyen d'au moins une séquence de brouillage périodique organisée en K intervalles de temps (20, 22) comprenant chacun N périodes de bits (21) appelées symboles. Un tel procédé comprend en particulier une étape de calcul d'une valeur de synchronisation d'au moins un polynôme générateur de ladite séquence de brouillage, en un intervalle de temps de synchronisation et en une période de bits de synchronisation prédéterminés. Il se caractérise avantageusement par le fait que lors de l'étape de calcul, on progresse dans la séquence par sauts d'au moins un intervalle de temps et d'au moins une période de bits, en mettant en oeuvre un calcul matriciel de la valeur de synchronisation.
