Patent ID: 8660166

Claim:
A method of synchronizing a receiver with a received ambiguous signal having a known number of at least two peaks, said method comprising: a) providing information about a known transmitted signal having a given number of at least two peaks, and the information including the number of peaks and the distances between the at least two peaks; b) determining ratios between the peaks of the known transmitted signal and assigning a determined ratio value to each peak; c) deducing a theoretical auto-correlation function from said known transmitted signal, wherein the auto-correlation function has a number of correlations corresponding to the number of peaks in the known transmitted signal and wherein correlators of the auto-correlation function are provided in a same distance and have a same relative ratio as the peaks in the known transmitted signal; d) tracking the received signal with the auto-correlation function so that a correlator pattern of the auto-correlation function is aligned with a peak pattern of the received signal by assigning each peak of the received signal to a correlator of the auto-correlation function; and e) identifying each peak.
