Abstract: A time and frequency synchronization method that includes the steps outlined below is provided. A wireless signal from a base station is received and orthogonal frequency-division multiplexing symbols of a primary synchronization signal of the wireless signal on a time domain is identified. The orthogonal frequency-division multiplexing symbols are transformed to a frequency domain to generate original symbol signals. An inner product of the original symbol signals and the received symbol signals is generated to obtain a product of a power leakage coefficient and a channel gain. A line search is performed to approximate an actual value of a fractional carrier frequency offset of the wireless signal based on the power leakage coefficient.
