A system and method for synchronizing to a received signal in an IR-UWB receiver including sampling the received signal in a frequency that is less than a Nyquist frequency of the received signal; for each part of the sampled received signal that is equal in length to a synchronization symbol: calculating a cross-correlation between the synchronization symbol and the part of the sampled received signal that is equal in length to the synchronization symbol; calculating at least one autocorrelation, where each autocorrelation is performed between the results of the cross-correlation and the results of the cross-correlation delayed by a time lag that equals one or more time-durations of the synchronization symbol; accumulating the results of each of the at least one autocorrelation to obtain at least one coarse synchronization window; and analyzing the at least one coarse synchronization window to detect presence of the synchronization symbol in the received signal.
