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.
