A spatial channel propagation model is presented. Consider a uniform linear antenna (ULA) at the base station (BS) and narrowband signals transmitted at the mobile. In two types of propagating environments: indoor and outdoor, performance of low spatial correlation is investigated and some results are provided, which are significant to analyze the performance of diversity systems and configuration of array. The results also show that the configuration of array with either smaller angular spread or bigger angle of arrival (AOA) dominates the impact on spatial correlation, and that increasing angular spread or decreasing AOA diminishes, or even eliminates this impact.
