Abstract
In this paper, we investigate the performance of multi-hop wireless networks with amplify-and-forward (AF) relaying operating in interference-limited environments. The analysis considers the presence of co-channel interferers that are scattered according to independent spatial Poisson point processes around the relays and the destination. Assuming that both the desired and the interfering signals experience Nakagami-m fading, exact expressions for the average bit error probability and the average channel capacity of the considered system are obtained as single integrals that can be reliably evaluated numerically. In addition, the diversity and coding gains per hop are obtained. The novel expressions can be used to show the impact of system and interference model parameters on the performance of multi-hop wireless systems. Simulation results are further provided to demonstrate the accuracy of the analytical expressions.
