A synchronization method and apparatus for synchronizing a receiver, such as a radiotelephone operable in a cellular communication system with a transmitter. Synchronization signals are transmitted as parts of a control signal to the receiver. Such synchronization signals are of high margins and also permit synchronization of the radiotelephone responsive to a reduced number of calculations. The time for such synchronization is reduced by use of nonlinear transformation metrics, such as logarithmic metrics, which reduce the impact of a noise or error component within the control signal.
Procédé et dispositif de synchronisation servant à synchroniser un récepteur, tel qu'un radiotéléphone, fonctionnant dans un système de communication cellulaire, sur un émetteur. Des signaux de synchronisation sont transmis au récepteur en tant que composantes d'un signal de commande. Ces signaux de synchronisation sont des signaux de paramètres élevés et permettent également de synchroniser le radiotéléphone sensible à un nombre limité de calculs. La durée nécessaire à cette synchronisation est limitée au moyen de paramètres de transformation non linéaires, tels que des paramètres logarithmiques, qui diminuent l'impact d'une composante de bruit ou d'erreur à l'intérieur du signal de commande.
