Title: Analysis of Spatial Diversity in Dense Ad hoc Networks

Authors: Raymond Louie, Iain Collings, Matthew McKay

Abstract: We investigate the performance of spatial diversity techniques in dense ad hoc networks. We derive analytical expressions for the density of interfering nodes in systems employing MIMO-MRC or OSTBC, subject to an outage and SIR constraint. In the case of MIMO-MRC, the expressions are based on new expansions for the SIR distribution in the high interference regime typical in dense networks. Our results are confirmed through comparison with Monte Carlo simulations.
