In a related carrier frequency offset estimation apparatus without increasing the power consumption, since it is difficult to estimate accurately the frequency deviation over a wide range, carrier frequency offset estimation apparatus of the present invention, an input signal, the input and resampling means for converting the oversampled signal oversampled at a multiple of the signal symbol rate, the time to calculate variation vector calculation time variation vector between temporally successive two sample signals included in the over-sampling signal comprises means, filter means for calculating an average value of the time-varying vector, the frequency deviation estimating means for calculating a carrier frequency offset estimate based on the average value, and.
