SVM-Assisted Realization and Demonstration of Indoor 4 Mb/s Non-Line-of-Sight Visible Light Communication With Second-Order Reflection

IEEE Photonics Journal, 2019
Non-line of sight (NLOS) visible light communication (VLC) from reflections can expand the application of VLC beyond the line-of-sight (LOS) link. We demonstrate the experimental results on such indoor NLOS VLC, up to the second-order reflection.
