Abstract
The effects of unreliable backhaul links on cognitive relay networks with best user selection over Nakagami-m fading are investigated. In particular, closed-form expressions for the critical performance metrics are derived along with the asymptotic performance to obtain insights into the impact of the backhaul reliability and multiuser scheduling. Our results demonstrate that backhaul link reliability is a key factor that imposes limitations on the performance of multiuser relay networks.
