A new method is proposed for estimating the velocity of wideband mobile stations (MSs) equipped with multiple antennas. The MS speed is determined using the well-known relationship between the direction-of-arrivals (DOAs) and the Doppler frequency shifts experienced by the multipath signal components. The method is based on the assumption that the multipath signal components with the DOAs confined to a small angular interval are clustered in the delay domain. Additionally, we assume that different intervals of the DOAs correspond to different intervals of the propagation delays. The performance of the proposed method is assessed by simulations. The algorithm has a low computational cost and is therefore suitable for realtime implementations.
