Single-channel wireless transmission at 806 Mbit/s using a white-light LED and a PIN-based receiver

For the first time, we present optimized indoor visible light links at up to 806 Mbit/s using a single channel of a low-cost off-the-shelf RGB-LED. While the RGB-LED acts as transmitter, a high bandwidth Si-PIN photodiode is used at the receiver. Discrete multitone modulation (DMT) is applied to optimally adapt to the channel corresponding to each color. With illumination levels in the range of normal working environments at the receiver, the resultant BERs are below the forward-error-correction limit for standard correction mechanisms.
