Abstract

In this paper, we investigate the impacts of unreliable backhaul connections on cognitive heterogeneous networks with best relay selection. Since spectrum sharing is employed, the transmit powers of the small-cell transmitter and relays are constrained by the peak interference at the primary user, as well as their maximum transmit powers. The closed-form expressions of the outage probability, ergodic capacity and symbol error rate are derived along with the asymptotic performance to get full insights. Our results show that the backhaul reliability is a limiting factor of the system performance.
