Abstract

The maximum Doppler frequency, or equivalently, the mobile speed is very useful information to optimize the performance of many wireless communication systems. In this paper, an improved method for the maximum Doppler frequency estimation based on the level crossing rate (LCR) estimator is proposed. To reduce the effect of additive noise, the proposed algorithm uses a novel Doppler adaptive noise suppression (DANS) process in frequency domain. The proposed DANS process does not require additional channel information such as signal-to-noise ratio (SNR).
