Abstract: A time and frequency synchronization method that includes the steps outlined below is provided. A wireless signal from a base station is received. The wireless signal is delayed on a time domain and is further correlated with the original wireless signal to generate a delayed and correlated signal. Primary symbols related to a primary synchronization signal are delayed and are further correlated with the original primary symbols to generate delayed and correlated primary symbols. The delayed and correlated signal and the delayed and correlated primary symbols are correlated to identify the position of the primary synchronization signal based on a primary peak value. The position of the secondary synchronization signal is identified based on the position of the primary synchronization signal.
