Outage Performance of NOMA with Interference over κ-μ Shadowed Faded Channels

Abstract Non-orthogonal multiple access (NOMA) is an emerging multiple access technique to provide higher spectral efficiency and data rates for future wireless communications. In this paper, outage probability expressions are obtained for NOMA over κ - μ shadowed faded channel, which can be applied to analyze the performance in mobile, satellite and underwater communication. Initially we observed the signal to interference (SIR) at user equipment (UE) by considering the inter and intra cellular interference. The outage probability expressions are obtained for NOMA with maximum ratio and selection combining. In this paper, we also calculated the outage results with random number of interferers. The analytical results are presented for two users which are at near and edge positions of a Voronoi cell. Finally, simulated results are presented to validate the analytical expressions.
