This chapter analyzed a downlink NOMA network with impacts from jamming signal. With regard to impairment of SIC, that is, imperfect SIC and perfect SIC were used in the receiver to provide a comparative study. To examine system per-formance, the outage probability was considered in this chapter under various para-meters. Specially, we derived the closed-form expressions for the outage probability. In order to evaluate other metrics, the throughput of the system is studied and system performance remains stable at high SNRs. These results can be achieved and verified by the simulation results and they were also further evaluated under varying the number of jamming sources. In future work, more users and more pairs of the group need to be investigated to implement such scenarios in real IoT systems.
