Performance analysis of downlink NOMA relying energy harvesting and full-duplex

Abstract

This paper considers the implementation of wireless power transfer scheme to non-orthogonal multiple access (NOMA) network at downlink. The single antenna power beacon (PB) provide capability of wireless charge to two NOMA users. In addition, full-duplex (FD) scheme is employed for two users. Outage probabilities related to system performance are evaluated in the scenario of the multi-antenna base station. Improved performance can be achieved since multi-antenna, energy harvesting capability. In particular, expressions of outage performance are derived in this system model to help to forward to serve far NOMA users. As the main advantage, NOMA and full-duplex schemes are two advantages and such a system is deployed to enhance the spectral efficiency. Our simulation results will indicate that main parameters such as a power allocation strategy, energy harvesting time, self-interference factor are the main impacts on considered system. The correct derived expressions are presented by matching Monte-Carlo simulation curves and analytical curves in numerical result section. As our main results, FD NOMA system corresponding the first user and the second user exhibits better than OMA 30% and 25% respectively when SNR at the source is 30 dB.
