Abstract

This paper investigates the performance of two-tier femtocell networks with cochannel femtocell deployment while considering cellular geometry and cross-tier interference in downlink. We derive the per-tier outage probability by introducing a simplified mathematical model that provides closely approximate femtocell interference distribution. Based on the outage probability analysis, we also derive the transmission capacity that represents the total capacity of the cochannel two-tier networks with outage constraints. The performance analysis provides an accurate characterization of the outage probability and the transmission capacity, accounting for the density of randomly scattered femtocells and femtocell transmission power.
