Abstract:
We consider radio frequency-energy harvesting (RF-EH) non-cooperative system, and, an RF-EH relay-assisted, two hop, hybrid cooperative communication system that comprises of a digital link, and an analog link that uses phase modulation. For the two system models, we analytically characterize outage probability when the node transmissions undergo small scale fading as well as path loss. In the analysis, we develop simple yet insightful closed-form expressions for outage probability. We validate our analytical results with Monte-Carlo simulations. Our numerical results show that the outage can be significantly improved by using pre-emphasis and de-emphasis (PE-DE)
