Abstract
5G networks and wireless power transfer are the topics that have attracted both academic and industry communities in recent years. In this paper, we study the cooperative transmission of uplink non-orthogonal multiple access (NOMA) network with wireless power transfer in terms of performance analysis. Specifically, energy-constrained amplifyand-forward relay cooperates with two users that applying NOMA scheme to transmit the message to base station by using the energy harvested from base station. For performance analysis, we derive the closed-form expressions of outage probability and throughput for two users based on the statistical characteristics of signal-to-noise ratio (SNR) and signalto-interference-plus-noise ratio (SINR) by using the Gaussian-Chebyshev quadrature method. To understand more detail of the behaviour of this considered system, the numerical results are provided according to the system key parameters, e.g., transmit power, distances. Furthermore, the theoretical results are also verified by the Monte-Carlo simulation.
