A scheme for the Doppler shift estimation despite the power control in mobile communication systems
Xiaohu You · Journal of China Institute of Communications · 2004
The characteristics of phase difference in the 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 coefficients on the effective fingers. Also we recommend an improved estimating method to get the high estimation accuracy in all kinds of velocity and signal-to-noise ratio.
