Abstract
In this paper, an adaptive Doppler shift estimator based on the square envelope autocorrelation function of the mobile propagation channel is proposed. Furthermore, the proposed estimator exploits the iterative minimum finding procedure to reduce the effect of additive noise. Both the theoretical analysis and the experiments are provided to show that the proposed method yields fairly good signal-to-noise ratio (SNR) insensitive performance in a wide range of velocities and SNRs
