Real-Time 262-Mb/s Visible Light Communication With Digital Predistortion Waveform Shaping
A digital predistortion waveform shaping scheme combined with a blue filter is proposed to optimize both the rise and fall times of a light-emitting diode (LED) and the optical receiver current of the signal of the real-time visible light communication (VLC) system.

| Summary: | A digital predistortion waveform shaping scheme combined with a blue filter is proposed to optimize both the rise and fall times of a light-emitting diode (LED) and the optical receiver current of the signal of the real-time visible light communication (VLC) system. The proposed scheme is implemented on a field-programmable gate array (FPGA) and a digital-to-analog converter based test bed, which is flexible and reconfigurable by programming the FPGA to match different LED characteristics and varied data rates. A 262-Mb/s non-return-to-zero on-off keying modulation based real-time VLC link with a bit error rate of less than <inline-formula><tex-math notation="LaTeX">$1.0\times 10^{-6}$ </tex-math></inline-formula> is achieved over a transmission distance of 5.0 m, which uses a single white phosphorous LED with a limited power of 0.1 W. |
