Abstract

La présente invention concerne un circuit de synchronisation et un procédé permettant de réaliser une synchronisation rapide et précise. Ce procédé consiste à réaliser une synchronisation parallèle ainsi qu'une corrélation à un niveau inférieur au niveau binaire. Le signal reçu est fourni en entrée à un numériseur (41) dont la sortie est soumise à un registre à décalage (43). Ce registre à décalage (43) dispose de 16 sorties, chacune de ces sorties aboutissant à un corrélateur (42) d'un jeu de corrélateurs. Chaque sortie du registre à décalage (43) représente la partie numérisée de la chaîne. Cette configuration permet d'utiliser le jeu de corrélateurs (42) pour faire les corrélations s'appliquant aux chaînes (31-38).
