Performance Analyses of NOMA Systems in Presence of Adversarial Jammer

In this paper, a single input single output Non-Orthogonal multiple access (NOMA) communication networks over a Rayleigh fading channel in the presence of an adversarial jammer is considered. The impact of different jamming techniques (Barrage Jamming, Partial-Band Jamming, and two schemes of Pulse Jamming) on the outage probability of the NOMA system is analytically derived. The throughput of the NOMA system is also analytically derived in the presence of the mentioned jamming techniques. In the end, a comparison among the different jamming techniques is held to propose the optimum jamming technique against the NOMA communication system according to the appropriate application of the adversarial jammer. All the derived analytical results are validated by extensive Monte-Carlo simulation results.
