Abstract
OFDM scheme is considered to enhance the data rate of visible light communication using lighting LEDs. In implementing this system, the inherent nonlinearity of LEDs is one of the factors of performance degradation. In this study, this LED nonlinearity is compensated by predistortion and performance enhancement is shown. Characterization and predistortion procedures of LEDs are proposed and experimental results are provided.
