Abstract: The present invention describes a synchronizing method and device enabling a receiver to adjust its time base to that of a base station. Such a device includes a frequency synthesizer programmed to one of the operating frequencies of the system; storage means STO having m locations REG1 to REGm and enabling the TDMA frames transmitted by the base station to be stored; correlation means COR which calculate in parallel products of the correlation of a part of the contents of the locations with a portion of a synchronization message containing the synchronization word SYNC; and a controller CONT which interrupts the correlation means as soon as a synchronization message containing a base station identification recognized by the receiver is found, and which ensures the synchronization of said receiver with the base station, which is effected on the basis of the determination of the position of the synchronization message in the location of the receiver.
