Abstract
We experimentally demonstrate a 750 Mb/s real-time visible light
communication (VLC) system based on non-return-to-zero on–off keying
modulation by employing single commercially available monochromatic
light-emitting diodes. To enhance the 3-dB bandwidth of the VLC link, we
propose a low-complexity cascaded post-equalizer based on NPN transistors.
With two different frequency-selecting networks in our post-equalizer, the
highest achieved 3-dB bandwidth of the VLC link is 370 MHz. The highest
achieved data rate is 750 Mb/s at a communication distance of 170 cm with
a bit error rate below 1×10−6, which is far below the forward
error correction limit (3.8×10−3). Based on our monochromatic
VLC system, a wavelength-division multiplexing VLC system could be
designed with a higher data rate.
