Performance Analysis of Blue Led-Based Visible Light Communication Using One-Dimensional Multidiagonal Codes

Visible light communication (VLC) is a powerful technology that is already in use in various application areas, such as indoor VLC, outdoor - vehicle to vehicle communication and under water communication. In this study, we present a VLC system design utilizing blue Light Emitting Diodes (LEDs) along with Multi-Diagonal (MD) codes. Based on the blue spectrum, the performance of this system is analysed using Opti-system software with Bit Error Rate (BER) and Quality factor (Q). Simulation results reveals that at data rate 100Mbps, the system achieves BER of 2.38744e-012 and Q-factor 6.43 over a link range of 1.3Km. Furthermore, performance analysis shows the impact of increasing the link range on BER & Q-factor and it has shown that using MD codes, VLC is reliable at longer distances making the proposed system suitable for diverse VLC applications. These finding underscore the potential of blue LED-based VLC systems in achieving efficient and scalable Optical Wireless Communication
