Abstract

A three-dimensional model is proposed for simulating the wireless channel. The model allows simulation of the effects of realistic channels on space-time processing and coding systems. The model is characterized by a set of scattering centers with a given mean angle of arrival (departure), angle spread (azimuth and elevation), and propagation delay. Additionally, the model accommodates either transmitter or receiver motion. Spatial characteristics of the simulated channels match previously obtained analytical results. We use the model to generate standardized temporal and spatial channel conditions from Global System for Mobile communication and third-generation standards. We demonstrate the need for such a spatial description by contrasting our results to classic methods of generating these standardized channel conditions.
