HIGH SPEED 100 GBPS VISIBLE LIGHT COMMUNICATION LINK EMPLOYING SINGLE CHANNEL PDM-QPSK AND DSP

Abstract

With the tremendous increase in the high capacity demands in sixth generation (6G) wireless networks, Visible light communication (VLC) is turned up as efficient and appealing candidate. In this work, a single channel 100 Gbps VLC system is presented by incorporating polarization enabled multilevel modulation and digital signal processing (DSP). Effects of different VLC link lengths, and transmitter half angles are explored in terms of Q factor, log symbol error rate (SER), log bit error rate (BER) and error vector magnitude percentage (EVM%). Results revealed that proposed system can cover 14 m link distance using lower transmitter half angle and DSP for multifarious functions such as nonlinear and linear compensations, normalization, and phase error compensation.
