- Abstract
This study explores the experimental performance analysis of indoor visible light communication (VLC) system using white LED sources. A total of nine LED sources are symmetrically arranged over the ceiling of the room of 1.7 × 1.7 × 1.8 m3 dimensions. For measuring illumination values, two distinct trajectories i.e. one along the middle path and another along the diagonal path are considered over the receiver plane. Moreover, the height of the receiver plane is also varied from 0.2 m to 1.2 m in steps of 0.1 m above the ground surface. The results show that the illumination values lie in the range of 20–100 lx for the working area of both the considered trajectories. Furthermore, real-time information in the form of RGB image is transmitted at a data rate of 40 Mbps and the received image quality is quantitatively analyzed for three distinct receiver locations namely corner position [0.1, 0.1], side position [0.85, 0.1], and center position [0.85, 0.85] in terms of structure similarity index (SSIM). The results show that the image is successfully transmitted (SSIM approx 99%) over the center position [0.85, 0.85] at all the considered heights of the target plane. An effort is also made to enhance the system performance by deploying median and wiener filters. Additionally, a comparison is presented between the simulation and experimental results. The results obtained reveal that the experimental and simulation results are in close agreement with each other and hence signifies the precision of the proposed VLC system.
