Decoding Method Comparisons In Light-To-Camera Communication

Visible Light Communication (VLC) is considered as a promising future wireless communications technology. Light-to-camera is one of the VLC key technique using CMOS sensors Camera captures flickering LED and gets the data. The information captured in the camera in the form of light and dark bands. The data receiving rate is decided by band detection level. Therefore, various detection methods are researched in recent studies. In this paper, we tested three threshold setting methods performance on Non Line-of-sight (NLOS) Light-to-Camera. We compared Subtraction image, Polynomial regression and Moving average by measuring speed and accuracy in both sides.
