Abstract: A method and apparatus are provided. The method includes receiving a reference signal from a transceiver, estimating a time offset (TO) of the reference signal in the frequency domain based on an accumulation of subcarriers before cross-correlation, providing a TO compensated signal of the reference signal based on the estimated TO in the frequency domain, transforming the TO compensated signal into the time domain, and estimating a frequency offset (FO) based on the time domain TO compensated signal.
