Single LED Gbps Visible Light Communication with Probabilistic Shaping

Using a single low-power LED, we present a probabilistic shaped (PS) VLC system with near Shannon capacity transmission rates. For the channel conditions under consideration and a single 21 MHz -3 dB modulation bandwidth LED, probabilistic shaped symbols resulted in Gbps transmission rates. Comparatively, the PS resulted in above 27 % higher transmission speed than the widely used adaptive bit-power loading algorithm under the same channel conditions
