A NOVEL INDOOR VISIBLE LIGHT COMMUNICATION SYSTEM USING MIMO TECHNIQUES AND LED PLACEMENT FOR ENHANCED SIGNAL QUALITY

Abstract

This paper presents a novel approach to enhancing the performance of indoor Visible Light Communication (VLC) systems by integrating Multiple-Input Multiple-Output (MIMO) techniques and a arrangement of Light Emitting Diodes (LEDs). With the increasing demand for high-speed wireless communication, VLC offers a promising solution, leveraging the unlicensed visible light spectrum. In this work, we investigate the potential of MIMO for improving data throughput, signal-to-noise ratio (SNR), and overall system efficiency in VLC systems. The proposed system utilizes a 3D LED configuration, which optimizes coverage and illuminance within indoor environments. Simulation results demonstrate the effectiveness of the proposed system in enhancing data rates and reliability, particularly when compared to traditional Single Input Single Output (SISO) systems. Furthermore, the paper explores the impact of different parameters, such as the use of optical lenses and varying LED distances, on the performance of the system. The findings highlight the significant improvements in system performance, making the proposed VLC architecture a strong candidate for future indoor communication applications.
