Modelling of High Speed Long-Reach LiWi-OCDMA System

In this paper, an integrated light fidelity-optical code division multiple access (LiFi-OCDMA) system for high-speed and long-reach applications has been presented. The results shows that the proposed system offers faithful transmission fiber and visible light communication (VLC) range are 150km and 1500m respectively, at 33Gbps data rate. It also supports 185 users using shift zero cross-correlation (SZCC) code and performs better than other existing systems.
