  Abstract

In a visible light communication (VLC) system using LEDs, its nonlinearity degrades the performance. If it is compensated by using predistortion and LED's linear range is extended, then a large signal can be used as an LED input and the performance of VLC will be improved. In this paper, a predistortion curve is made by periodic measurement of LED nonlinearity, and the experimental results of predistorted OFDM is provided.
