A method for estimating frequency offset is provided. First, a baseband signal with a preamble featuring quasi-periodic property is received. Next, the quasi-periodic property of the preamble of the received baseband signal is reconstructed by interpolation. Next, a frequency offset angle is estimated by using the reconstructed baseband signal. The accuracy of estimating frequency offset is increased because of better reconstructed quasi-periodic property of the preamble.
