Verfahren zur Trägerfrequenzsynchronisation

摘要

Described is a method of synchronizing carrier frequencies in a mobile-radio network with base and mobile stations, the base stations broadcasting a synchronization signal which is received by the mobile stations and used to derive their transmission frequency. The base stations emit as the synchronization signal a family of sine waves of different frequencies. Each of the mobile stations has a selection filter by means of which at least one of the emitted sine waves can be detected. The method is insensitive to fading and permits extensive standardization of the circuits in the base stations and in particular standard processing facilities in the mobile stations.
