Abstract

In the visible light (VL) communication based on the multicolor channel between colored LEDs and photodiode, a uniform performance on color channel may be desired, and VL communication services using multiple color channels should be attained by only one VL receiver. However it has been known that the received signal has the severe color distortion by the receiver performance variation on multicolor channels since photodiode produce more electrical current on red color than on green or blue color channel. In this paper we estimate the compensation extent of the color distortion in advance by color map and utilize the optimal VL transceiver circuit for distortion-less VL communication in the multicolor VL channel. We can see that the conventional technique without any compensation function of color distortion effect meets a failure in the color VL communication trial because of the different VL communication distance on each color VL channel, but the proposed scheme has no distortion due to the performance variation of each color VL channel in the overall range of communication distance.
