Abstract
In this paper, we demonstrate a high-speed visible light communication system employing a 520-nm green laser diode. A recorded data rate of 15.004 Gbps is reported by utilizing an adaptive bit-loading discrete multitone (DMT) modulation scheme with a measured bit error ratio (BER) of $3.724 \times 10^{-3}$, which satisfies the forward-error-correction (FEC) criteria. The results suggest the system has a high spectral efficiency of 5.456 bit/s/Hz at 2.75 GHz bandwidth.
