Abstract
An apparatus for estimating carrier frequency offset includes an Mpower circuit, a spectrum generating circuit, a peak frequency determining circuit and a frequency offset determining circuit. The Mpower circuit performs an Mpower calculation on an input signal to generate an Mpower calculation result. The spectrum generating circuit generates an Mpower spectrum according to the Mpower calculation result. The peak frequency determining circuit determines a peak frequency corresponding to an amplitude peak from the Mpower spectrum. The frequency offset determining circuit determines an estimated carrier frequency offset according to the peak frequency.
