Description
Summary:	The spatial correlation in satellite downlink MIMO systems influence the maximum achievable capacity. As higher Rician factor leads to reduced spatial correlation effects, it is essential to analyze the influence of Rician factor over system performance. In this work, Loo channel model is considered. The probability density function of this model exhibits a non-zero mean emphasizing the presence of LOS component in addition to scattering and multipath fading effects and hence leading to high Rician factor. Critical parameters such as channel capacity, dependence of antenna spacing on correlation coefficient and outage capacity for 1% to 10% outage probability are analyzed for LMS MIMO system considering spatial correlation effects.
