Abstract:
1. A method for detecting a received synchronization signal, the method comprising: receiving, at a receiver, a signal from a transmitter, wherein each of one or more portions of the received signal includes the received synchronization signal; processing the one or more portions of the received signal to obtain a differential signal; processing the differential signal and a plurality of candidate differential synchronization signals to obtain a plurality of cross-correlation signals, wherein each candidate differential synchronization signal is associated with one of the plurality of cross-correlation signals; selecting, based at least in part on the plurality of cross-correlation signals, one of the plurality of 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 a cross-correlation signal that is associated with the selected candidate differential synchronization signal.
