Abstract

With the stringent requirements of fifth-generation and beyond wireless communications technology coupled with the potential bottleneck in the optical fronthaul, radio-over-fiber (RoF) technology offers an alternative solution to distribute the wireless signals while meeting these requirements. The inherent centralized architecture of RoF enables advanced coordination functionality to be performed within the fronthaul network. Advanced coordination functionality such as non-orthogonal multiple access (NOMA) has gained traction as a means to improve spectral efficiency for larger user-base networks. Among various NOMA implementations, the recently proposed multilevel code (MLC) was found to b..
