  • Publication number: 20190273646
    Abstract: An apparatus for estimating a carrier frequency offset (CFO) is provided. A differential correlation calculation is performed on a received signal and a reference signal to generate multiple calculation results. One among M number of peak values with largest amplitudes determined from the calculation results is selected as a candidate peak value and outputted each time. A data capturing circuit captures from the received signal a data segment corresponding to the candidate peak value as a candidate data segment. A fast Fourier transform (FFT) circuit performs FFT on a product of the candidate data segment and a conjugate signal of reference data to obtain a candidate transform result. A selecting circuit determines whether to select the candidate transform result as a target transform result. The CFO calculating circuit determines an estimated CFO according to a frequency corresponding to the largest amplitude in the target transform result.
