In this paper, we experimentally realized a gigabit-class indoor
visible light communication system using commercially available RGB
White LED and exploiting an optimized DMT modulation. We achieved
data rate of 1.5 Gbit/s with single channel and 3.4 Gbit/s by implementing
WDM transmission at standard illumination levels. In both experiments, the
resulting bit error ratios were below the FEC limit. To the best of our
knowledge, these values are the highest ever achieved in VLC systems.
