This letter presents two outage-optimal relaying schemes to improve the performance of a wireless energy harvesting system in cognitive radio networks. The performance of both schemes is then evaluated and compared by carrying out numerical simulations, and we also derive the analytic expression for the outage probability of the secondary system.
