Abstract

Non-orthogonal multiple access (NOMA) is an enabling technique to support massive connectivity and utilize the radio resources more efficiently. A number of novel NOMA schemes have been proposed for 5G New Radio (NR) standards. In this study, we evaluate various 5G NOMA methods for different military communications scenarios. First, we provide the description of basic principles in each evaluated scheme, then we investigate and compare their performances under different system parameters such as spectral efficiency, overload factor and antenna numbers in various channel models. Finally, we provide the discussions and insights on the suitability of the evaluated schemes for the considered military scenarios based on simulations.
