摘要:
Systems and methods are provided for detecting a received synchronization signal. The method includes receiving, at a receiver, a signal from a transmitter and the signal includes the received synchronization signal. The method includes processing the received signal and a plurality of candidate synchronization signals to obtain a plurality of correlation signals. Each candidate synchronization signal is associated with one of the plurality of correlation signals. The method includes selecting, based at least in part on the plurality of correlation signals, one of the plurality of candidate synchronization signals. The selected candidate synchronization signal is correlated with the received synchronization signal. The method includes detecting the received synchronization signal based at least in part on (i) the received signal, and (ii) a characteristic obtained from the correlation signal that is associated with the selected candidate synchronization signal.
