Outage probability of downlink noma energy harvesting for multiple users over rayleigh fading channels

Abstract

In this paper, we propose down-link non-orthogonal multiple access (NOMA) networks for multiple users with energy harvesting (EH). Over Rayleigh fading channels, we derive the closed form expression for the system outage probability (OP). Monte Carlo simulation is utilized to verify the correctness of the analytics results confirming the advantage of the proposed networks. The effects of key system parameters such as time allocation coefficient, power allocation coefficient, and average signal-to-noise (SNR) on the system performance are also investigated.
