We develop a simple yet accurate analysis of the interference distribution in a cellular system, with particular emphasis on a two-hop fixed relay network, though the analysis may apply to much wider contexts. Similar analyses have already been proposed, but suffer from being too specific in their assumptions, are analytically difficult, consider only the uplink, and are not necessarily validated. We provide a simple closed-form solution for a wide variety of cases and validate all our theoretical curves directly by Monte-Carlo simulations of the exact same models. Our method is flexible for many channel and system parameters, and for arbitrary cellular layouts, thus it can readily be applied to a two-hop relay context.
