Abstract
In this paper, we study the relay transmission of uplink non-orthogonal multiple access (NOMA) network in terms of performance analysis. Specifically, two users applying NOMA scheme intent to transmit the message to base station (BS) by the help of amplify-and-forward (AF) relay. The expressions of outage probability and throughput for two users are derived based on the statistical characteristics of signal-to-noise ratio (SNR) and signal-to-interference-plus-noise ratio (SINR) of transmission links by using Gaussian-Chebyshev quadrature method. In order to look into the behaviour of this considered system, the numerical results are provided using system key parameters, e.g., transmit power, distances. The Monte-Carlo simulation results are also provided to verify the correctness of our analysis.
