Abstract
Systems and methods are provided for detecting a received synchronization signal. The method includes receiving, at a receiver, a signal from a transmitter, where one or more portions of the received signal include the received synchronization signal. The method includes processing the one or more portions of the received signal to obtain a differential signal, and processing the differential signal and a plurality of candidate differential synchronization signals to obtain a plurality of cross-correlation signals. Each candidate differential synchronization signal is associated with one cross-correlation signal. The method includes selecting, based at least in part on the plurality of cross-correlation signals, one of the candidate differential synchronization signals, and detecting the received synchronization signal based at least in part on (i) the one or more portions of the received signal, and (ii) a frequency offset value obtained from the cross-correlation signal associated with the selected candidate differential synchronization signal.
