Claim Text:
1. A method for receiving a synchronization signal transmitted by a radio transmitter using at least two different first frequencies, each of the at least two first frequencies being within a corresponding one of at least two first temporal intervals separated by a different respective first duration, said first temporal intervals being of identical length, said first durations have a different length for each of said at least two different first frequencies, the method comprising: a first step of, using a radio receiver, receiving and demodulating the synchronization signal, said demodulation being carried out using a locally generated second frequency; a second step of, using the radio receiver, determining: (1) at least two second temporal intervals in which an energy of the demodulated synchronization signal is at a maximum, and (2) at least one second duration separating the at least two second temporal intervals; the second step further including comparing the at least one second duration and said first durations in order to determine at least one gap between at least one of the first frequencies and said second frequency; and a third step of synchronizing the radio receiver to the synchronization signal using said at least one gap.
