Performance Analysis of MIMO Using Diversity Technique in VLC FSO Communication Systems

Visible Light Communication (VLC) is a growing trend in future communication technology. In VLC systems, Free Space Optics (FSO) is used as the transmission medium. These VLC FSO systems offer solutions to congestion problems in RF communication by providing similar frequency range scalability, cost-effectiveness, and mobility. However, challenges such as weather conditions like smog and storms, as well as the need for a clear line of sight, pose significant hurdles. In this paper, we purpose a reliable VLC system that uses MIMO with RZ, NRZ and QPSK coding with filters and amplifiers to improve performance. The system is tested over a 1500-meter link distance, achieving a simulated data rate of 10 Gbps. This proposed system is suitable for high data rate communication in VLC, with the potential to extend transmission distances by reducing signal fading in free space
