Outage Probability and Capacity Analysis for NOMA based 5G and B5G Cellular Communication

Abstract

This study presents a non-orthogonal multiple access (NOMA) solution for 5G that unifies communication betweenmacro-cells via the S-R NOMA link and communication between small cells via the R-D NOMA link. S-R NOMA isused to decode own signal by respective relay. Separate studies of outage performance in S-R and R-D connectionsmay formerly be used to get an accurate definition of system outage likelihood. Our mathematical analysis issupported by simulation findings, which indicate that NOMA-assisted relaying systems outperform OrthogonalMultiple Access systems in terms of lower outage probability and better cumulative capacities (OMA).
