Abstract

a) L'invention concerne un procédé pour déterminer la coïncidence entre la position de phase du code d'un signal modulé reçu par un récepteur et du code produit dans le récepteur. b) Ce procédé est caractérisé en ce qu'on prélève sur un signal à fréquence intermédiaire une fraction de signal de largeur supérieure à celle de la bande de base, on prélève en outre une fraction de signal dont la fréquence est située à l'extérieur et on compare les puissances des deux fractions. c) L'invention est essentiellement applicable aux transmissions par satellites.
