In the energy harvesting scheme, energy from the received information signal and co-channel interference (CCI) signals is scavenged by the self-power relay before it is used to amplify the received signal and finally transmit to the destination. Particularly, the closed-form outage probability expressions are evaluated for tractable performance analysis. In this paper, we also introduce the results of Monte Carlo simulation to prove the tightness of the proposed approximations outage performance. Additionally, it is assumed that the benefits of CCI signals can extend the lifespan of relaying systems and enhance energy efficiency at the self-power relay.
