Optimizations of Probabilistic Constellation Shaping Superposition Schemes for the MISO Visible Light Communication System

Two probabilistic-constellation-shaping (PCS) superposition schemes are proposed in the multi-input-single-output (MISO) visible-light-communication (VLC) system. Performance optimizations of 2.3Gbps MISO-VLC using global and local PCS superposition schemes are experimentally demonstrated in linear and nonlinear operation ranges.
