A Parametric Channel Model for Smart Antennas Incorporating Mobile Station Mobility

Abstract

This paper presents a parameterized physical channel model for evaluating the performance of smart antenna systems. The channel model assumes a single antenna at the mobile station and a uniform linear array of omni-directional antenna elements at the base station. It incorporates parameters such as azimuth angle of arrival and departure, angle spread, power delay profiles and Doppler frequency, which have critical influence on the performance of smart antennas. A new feature of the channel model is a thorough framework for the incorporation of user mobility. The proposed model allows for efficient and accurate representation of smart antenna channel aspects, while maintaining low complexity for system level simulations.
