Abstract
In this work, we consider employing the NOMA (Non-Orthogonal Multiple Access) technique in downlink VLC (Visible Light Communication) for performance enhancement. In particular, focusing on a typical NOMA scenario with two users, we optimize the power allocation strategies under both sum-rate maximization and max-min fairness criteria, where practical optical power and QoS (Quality of Service) constraints are included. As our main contribution, we achieve optimal power allocation solutions in semi-closed forms via mathematical analysis, which, to the best of our knowledge, have not been reported in literature. Simulation results demonstrate that NOMA can provide remarkable performance gains over OMA (Orthogonal Multiple Access) in the context of VLC downlinks.
