Demonstration of Non-Orthogonal Multiple Access Scheme using Multilevel Coding without Successive Interference Cancellation with 60 GHz Radio-over-Fiber Fronthaul

We propose a multilevel coding based non-orthogonal multiple access scheme for 60 GHz RoF fronthaul link and verify through experiments with error-free transmission over 3-km fiber and 2.5-m wireless link, serving two users at cell edge and center.
