A Doppler shift estimator in radio propagations



[1] Because of the development of wireless communications, mobile propagation has played an important role in the research of radio science. Therefore, we propose a precise scheme to estimate one of the most important parameters in wireless propagations: Doppler shift. The scheme utilizes an iterative processing to eliminate both the approximation error and the effects of additive noise. Moreover, both theory and simulation show a precise performance in a wide range of velocities and signal-to-noise ratios.
