Performance Analysis of Color-Independent Visible Light Communication Using a Color-Space-Based Constellation Diagram and Modulation Scheme.

In this paper, various aspects of a color-space-based visible-light communication (VLC) system design are explored, including feasible light color spaces, potential constellation diagrams, data-to-light intensity mapping, and light intensity-to-data demapping. After describing the proposed VLC system and parameters essential for a color-space-based VLC system design, numerous methods of constellation design for generating a target color in a light color space are presented. The proposed method also incorporates a technique to calculate light intensity from the constellation point. The performance of a proposed system is analyzed with an additive white Gaussian noise channel along with various color scenarios. We also investigate two cases to obtain the target color information at the receiver. Simulation results are presented in order to evaluate the performance of the proposed VLC system.
