| 摘 要： | 1. INTRODUCTION The received signals at base station (BS) usually suffer from fading due to multipath propagation1, 2]. The antenna arrays technology have been intensively employed for enhancing performance by mitigating multi-path fading and co-channel interference3,4]. With the ever-increasing demand for personal comm.- unication, antenna miniaturization technology trends become more and more important5]. Spatial correl- ation has always been greatly concerned. On the one hand, a co…

| Abstract: | 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. |
