| Outline of Final Research Achievements |
In this study, novel lighting constrained visible light communications (VLC) using digital controlled massive multi-color LED array are proposed for an intelligent Lighting system. For main technology for the VLC system, a digital color shift keying with multicolor led array is represented to avoid the effect of LED nonlinearity. Especially for high-speed VLC systems, a DCSK system using spatial shift keying and DCSK with code division multiplexing using Hadamard code with on-off signaling are investigated. Furthermore, for intelligent lighting system, DCSK systems with dimming control and target color control are also proposed and evaluated.
