ABSTRACT:
A process for synchronization of an input signal (S) involves demodulating (5a) the input signal (S) according to a particular demodulation method (AM) using a particular signal parameter for creation of a demodulated input signal (SAM); correlating (6a) the demodulated input signal (SAM) with a comparison signal (f (AM,Signal)) which depends on the demodulation method (AM) to determine a time offset (τ) between the demodulated input signal (SAM) and the comparison signal (f (AM,Signal)); and time displacing, or shifting, the input signal through the time offset (τ) calculated from the correlation.
