Energy Harvesting in $\alpha $ - $\mu $ Environment Under Different Relaying Protocols

In this letter, we consider dual-hop decode-and-forward relaying systems, where the relay node harvests the energy from the source node. In the literature, there are three main protocols for relaying/energy harvesting, namely, time-switching relaying, power-splitting relaying, and ideal relaying receiver protocols. In this letter, we derive a novel, exact, and unified closed-form expression for outage probability for the aforementioned protocols over independent but not identically distribute α-μ fading channels. The results show the positive impact of increasing the fading parameters on the system performance. Our analysis is verified through numerical and simulation results.
