For testing an adaptive array algorithm in cellular communications, we develop a geometry based statistical channel model that provides the statistics of angle-of-arrival and doppler spectra of the multi-path components, into which introduced are the new concepts of effective scatterers and reflection probability. This channel model is suitable for describing the outdoor and indoor propagation environments, which is applied to the performance of multiple input multiple output (MIMO) system. A comparison between our theoretical calculations and customary results shows that the analysis is correct and applicable to microcell environments, which can promote the research of the statistical channel models and provide accurate and flexible channel models for the MIMO multi-antenna systems.
