N2 - The problem of the frequency estimation of MPSK signal in unknown fading channel is too complicated and there is no research result for this problem at present, while we often meet these problems in practice. The method mentioned in this paper compensates the channel effects before the estimation the carrier frequency. This method is more simple and efficient than the method which uses frequency and channel impulse response for the joint estimation, and it is more convenient to remove modulation for MPSK signal. Compared with the frequency estimation research of non-fading channel, the estimation performance falls only about 3dB. So, this method can satisfy most application needs.
