Demonstration of Performance Improvement in Multi-User NOMA VLC System Using Joint Transceiver Optimization

The bit error ratio (BER) performance of a non-orthogonal multiple access (NOMA) visible light communication (VLC) system is poor due to the unequal distances between adjacent points in the superposition constellation (SC). In this paper, we propose a novel scheme to improve the BER performance by a...
