Investigation on NOMA based 60 GHz Radio-over-Fiber Fronthaul Links

Abstract

Advanced coordination scheme such as Non-Orthogonal Multiple Access (NOMA) is able to improve the spectral efficiency and fairness amongst users in a multi-user environment. However, the inherent issue associated with NOMA successive interference cancellation tends to degrade the performance of the link. This paper presents our work on multi-level code (MLC) NOMA to overcome this limitation and further study the impact of different clustering on 60 GHz radio-over-fiber based fronthaul links.
