Method and device for synchronization upon reception of a signal and echoes

The invention concerns a method for synchronization upon reception of a received signal obtained by adding a plurality of transmission signals, all corresponding to the same source signal comprising data blocks called symbols of predetermined duration. The invention is characterized in that it comprises: a step which consists in determining a signal representing inferences between the symbols called intersymbol inferences; a step which consists in determining times of minimum interference level which correspond to markers of the beginning of symbols and of said symbol duration, of the reception of said received signal. The invention is in particular applicable to terrestrial digital television.
