1. A method for estimating a frequency offset, comprising:
extracting sampling points from an input signal according to preset intervals to obtain a plurality of groups of sampling points, with the preset interval of the groups of sampling points being different;
performing processes on a current sampling point and the groups of sampling points to obtain data of arguments of complex numbers corresponding to the preset intervals; and
determining an estimation value of a frequency offset of a current input signal according to the data of arguments of complex numbers corresponding to the preset intervals.
