Outage Performance in Cooperative NOMA Systems with Energy Harvesting in Nakagami-m Fading

Abstract

This paper investigates cooperative non-orthogonal multiple access (NOMA) with energy harvesting (EH) radio networks. This promising technology is the key to address an important issue of next-generation wireless communication Systems. EH is a well known technique for reducing energy consumption of battery-limited devices by collecting energy received from high power equipments. Closed-form expression of outage probability is derived at relay assisted transmission scheme with Nakagami-m fading channels. Simulation results validate the proposed theorem. We consider the impact of time splitting fraction on system maintainability.
