Abstract

The increasing demand for mobile communication services without a corresponding increase in radio frequency (RF) spectrum allocation motivates the need for new techniques to improve spectrum utilization. An approach that shows real spectrum utilization for substantial capacity enhancement is the use of smart antennas. The smart antennas are capable of automatically forming beams in the direction of the desired signal and steering nulls in the directions of the interfering signals. Another approach that satisfies the demand for quality of services in a mobile communication system is the capability of the communication system to estimate and "predict" the location of a mobile user. In this paper we provide a system that tracks the position and estimates the velocity of a mobile user, using smart antennas on the base stations.
