Design and Analysis of a Scheme for the Doppler Shift Estimation
Xiaohu You · 2004
The Doppler-shift of the time-varying multi-path channel can be estimated by calculating the level crossing rate (LCR) of the signal envelope of the channel coefficient estimates on the effective fingers. Also some parameters relating to the Doppler shift are analyzed, and an improved estimation method to get the high estimation accuracy in all kinds of velocity and signal-to-noise ratio is raised.
