Outage probability of energy harvesting DF relay systems in generalized-K fading

Abstract

Decode-and-forward (DF) relay system where the relay node harvests energy from the source is analyzed, for the case when time-switching relaying protocol is applied. It is assumed that both source-to-relay and relay-to-destination links experience Generalized-K fading. The outage probability of DF system is analyzed and the accurate approximation is derived in the closed-form. Numerical results that show the impact of fading and system parameters are presented and discussed.
