Abstract

This paper presents the hardware design, implementation, and performance evaluation of a Visible Light Communication (VLC) system. The study begins with a description of the VLC system architecture, followed by an investigation of VLC modulation techniques, focusing on Binary Amplitude Shift Keying (BASK) and 4-level Amplitude Shift Keying (4ASK). The work further examines the impact of incorporating Hamming channel coding into VLC to improve error detection and correction performance. Additionally, experiments were conducted using different light sources (LED and Laser Diode) to assess their influence on signal quality and transmission range. A Multiple-Input Multiple-Output (MIMO) VLC configuration was also implemented to enhance system capacity and robustness. Comparative results demonstrate the trade-offs between the coded and uncoded systems, modulation schemes, light sources, and MIMO configurations, providing practical insights into the hardware realization and design of efficient VLC networks.
