Abstract

The Doppler shift, or equivalently the vehicular speed, represents the fading rate of mobile channels, thus its estimation must be important in the mobile communication system. This paper investigates the estimation of Doppler shift by taking into consideration the rate of minimum (ROM) of envelope, where both the iterative processing and polynomial fitting are employed to improve the estimating performance. We verify the proposed scheme by numerical simulations, and see the satisfying performance for variable speeds and SNRs.
