Abstract

In order to compensate the degradation caused by the frequency shift under the Rayleigh fading with vehicular mobility, it is necessary to devise a efficient phase estimation method. In this paper, three old methods and complex number method are presented and compared. It is concluded at last that the combination complex number method is better than other old methods which have some limited conditions.
