Abstract
In this paper, a new estimator for the velocity of a mobile station in a micro-cellular system is proposed. The proposed estimator is based on the instantaneous frequency of the received signal at the mobile station antenna. The performance of the proposed estimator in the presence of shadowing, additive noise, and non-isotropic scattering is analyzed, and compared with that of the conventional zero crossing rate based velocity estimator. We show that, unlike conventional estimators, the proposed estimator is robust to shadowing and additive noise.
