Abstract :
In this paper, we investigate an underlay relay-assisted cognitive radio network where a secondary relay harvests energy from a secondary source´s signal. Outage probability of the secondary network is derived in closed form under a harvested energy constraint at the relay and an interference constraint at the primary user. Also, optimal energy harvesting duration is obtained. Analytical results are verified by computer simulation.
