A method and apparatus is provided for synchronizing a received communication signal. A synchronization signal is derived from a received signal having a plurality of synchronization words. Each synchronization word has a predetermined number of synchronization symbols. The synchronization signal is filtered. The filtering is characterized by spacing each filter tap to correspond to synchronization word length increments. Synchronization information is generated which is based on a comparison of the filtered synchronization signal to a threshold. Finally, the synchronization information is output based on a confidence decision derived from the synchronization information.
Méthode et appareil de synchronisation d'un signal de communication reçu. Un signal de synchronisation est tiré d'un signal reçu comprenant un certain nombre de mots de synchronisation. Chaque mot de synchronisation a un nombre prédéterminé de symboles de synchronisation. Le signal de synchronisation est filtré. Le filtrage est caractérisé par l'espacement de chaque prise de filtre en fonction des incréments de longueur des mots de synchronisation. De l'information de synchronisation est générée en fonction d'une comparaison entre le signal de synchronisation filtré et un seuil. Enfin, l'information de synchronisation est produite en sortie conformément à une décision de confiance obtenue à partir de l'information de synchronisation.
