description The fifth generation (5G) mobile communication technology has the characteristics of high speed and large bandwidth,which makes the fading of radio signal in time domain and frequency domain more obviously.With the increase of differential values statistical step and the spatial sampling interval,the channel estimation method based on the differential probability can't track the deep fading area and the peak area was over-tacked.In view of the above problems,a channel estimation method based on quadratic differentials probability was proposed.Firstly,the valley point and peak point of the fading curve were found.Then,the estimated differential values of deep fading area and peak area were improved by quadratic differential probability.Finally,the estimated gains were obtained by the difference operation.Simulation results show that,this method can improve the whole tracking performance effectively and reduce the tracking error.
