PROJECT TITLE :
8-Gb/s RGBY LED-Based WDM VLC System Employing High-Order CAP Modulation and Hybrid Post Equalizer
During this paper, for the primary time, we have a tendency to propose the employment of a hybrid post equalizer in an exceedingly high-order carrierless-amplitude-and-part-modulation-based mostly visible lightweight communication (VLC) system. The hybrid equalizer consists of a linear equalizer, a Volterra-series-based mostly nonlinear equalizer, and a call-directed least mean squares equalizer to simultaneously mitigate the linear and nonlinear distortions of the VLC system. A commercially accessible red–blue–green–yellow light-emitting diode (RBGY LED) is utilised for four-wavelength multiplexing. By the hybrid equalizer, an mixture data rate of 8 Gb/s is experimentally achieved over a 1-m indoor free-house transmission with the bit error rate (BER) below the 7% forward error correction (FEC) limit of . To the best of our information, this can be the best data rate ever reported in high-speed VLC systems.
