On Outage Analysis in Cooperative Cognitive Radio Network with RF Energy Harvesting

In this paper, we investigate the performance of a cooperative cognitive radio network which supports both spectrum sharing and radio frequency (RF) energy harvesting using power splitting relaying (PSR) protocol. The system model consists of a pair of primary users (PUs), each one equipped with multiple antennas and a pair of secondary users (SUs), each one equipped with a single antenna. The secondary transmit node harvests energy from the received signal of PUs and use this energy for forwarding the PUs signals and its own message signal. The exact closed form expressions of outage probability for PU and SU system outage are derived. A large set of simulation results are reported that validate the analytical outputs.
