Comparison between Hybrid AMI and Duobinary–VLC (Visible light Communication) using WDM (Wavelength Division Multiplexing)–PI (Polarization interleaving) Transmission System

摘要

VLC is need of high-speed data rate transmission for next-generation networks. LOS communication is a must for a high-speed VLC communication system. In the VLC system, we have formed a high-speed Visible light communication system utilizing WDM, and PI scheme for broadcast information in the visible form of eight channels, each one bear 10 Gbps data accomplished by the VLC link of 160 m. We have compared performance improvement using AMI coding and duo binary coding. The bit rate of 10 Gbps up to 160m has been investigated using Q factor in eye diagrams and bit-error-rate (BER) which is targeted to achieve the value greater than 7 and less than 10–9 respectively. VLC system simulation is done on Optisystem 15. □
