Abstract

Abstract : In this Letter, a recorded single channel of 6.915‐Gbit/s white‐light visible light communication (VLC) system is reported and experimentally demonstrated. By optimising the bit‐loading algorithm onto the direct‐current optical OFDM signal and without using an optical blue filter, the high data rate can be achieved. After a free‐space propagation distance of 1.5 m, the white‐light beam diameter of 14 cm and illuminance of 795 lux are measured. The proposed white‐light VLC system can provide both lighting and communication simultaneously with functional propagation distance.
