Abstract:

Several Doppler shift estimators, including mean logarithm envelope difference(MLED)method, auto-correlation function(ACF)method, zero crossing rate(ZCR)method and mean square phase difference(MSPD)method are discussed and compared. The estimation principle and theoretical estimation bias of these estimators under Rayleigh fading channels are analyzed; furthermore, the Cramer Rao bound(CRB)of Doppler shift estimation is deduced, and a novel modification method based on two-dimensional polynomial fitting is proposed to reduce the Doppler shift estimation bias. We verify our algorithms with the Monte Carlo computer simulation; simulation results show better variance performance of modified methods than those of the original methods. In addition, the applicable situations of these estimators are discussed.
