  Abstract

In a color-independent visual-MIMO system using color-space-based modulation techniques, it is not easy to determine the color of a symbol captured by a camera. In this paper, the effect of noise can be minimized by applying the color quantization in the receiving end. Also, we propose a method to improve the accuracy of symbol decision using palette generated by considering channel environment. Finally, the proposed method is verified by comparing the position of a transmitted symbol with the position of a received symbol in the color space.
