Doppler frequency shift estimation for rician channel in high-speed mobile communications

In high-speed mobile wireless communication system, the side-effect of Doppler frequency shift is obvious. In order to get rid of it, the estimation of Doppler frequency shift is necessary. This paper proposes a new way to estimate the Doppler frequency shift with a new Rician channel model. The simulation results show that the estimate of Doppler frequency shift is more accurate with the proposed estimation method
