Abstract
The characteristics of phase difference in a time-varying channel are analyzed then the Doppler shift of the time-varying multi-path channel is estimated by calculating the expectation of the square phase difference of the channel coefficient estimates on the effective fingers. Also we recommend an improved estimation method to get a high estimation accuracy in a wide range of velocity and SNR (signal-to-noise ratio).
