Virtual MIMO Network A Physical Wireless Analysis

Executive Summary

By analogy with an approach widely used in physics, the authors consider a discrete set of Base Stations (BSs) as a continuum of transmitters. This model allows them to establish a simple closed-form formula of the interferences and the SINR received by a mobile, whatever its location. As an application of this model, they propose an analytical study of a virtual MIMO network. Indeed, they consider that the useful power received by each user of a cell is the sum of useful powers coming from all base stations of the network. The physical wireless network model enables to quantify, in a simple way, the impact of virtual MIMO on the instantaneous throughput. They moreover show that the outage probability increases.
