We propose a novel OFDM-NOMA bit and power loading algorithm for hybrid unicast and broadcast downlink and demonstrate in 1.1~1.9-Gbit/s cooperative VLC experiments that the proposed algorithm outperforms conventional OFDM-NOMA, DFT-S OFDM-NOMA, and OCT-P OFDM-NOMA regardless of the unicast/broadcast data rates and channel conditions.
