1. A method of performing synchronization and frequency offset estimation, the method comprising:
receiving an input signal corresponding to a single training sequence;
generating phase information and a phase index by performing an auto-correlation function (ACF) on the input signal;
generating a templet signal associated with a sample index of the input signal based on at least one pre-stored look-up table, the phase index, a frequency bandwidth of the input signal, and the sample index;
calculating power associated with the sample index by performing a matched filtering on the input signal based on the templet signal; and
simultaneously determining a synchronization timing and a frequency offset for the input signal based on a result of the matched filtering.
