Downlink Outage Probability Analysis of D-MIMO Systems over a Composite Channel

Abstract:

This paper concerns with the analysis of the downlink outage probability of D-MIMO systems over a composite channel. Firstly, a composite fading channel is established by integrating Nakagami-m fading, shadowing and path loss; next, a step-decreased mobile station (MS) distribution is proposed, which is more suitable for a real communication environment due to its varying-parameter property in probability density function (PDF); then, an approximate closed-form formula for downlink outage probability with arbitrary MS distribution is deduced by using several mathematical methods; finally, by taking the proposed MS distribution model into account, the derived downlink outage probability expression is further verified by computer simulation results.
