Channel characterization in screen-to-camera based optical camera communication

With the increase in optical camera communication (OCC), a screen to camera-based communication can be established. This opens a new field of visible light communication (VLC) known as smartphone to smartphone based visible light communication (S2SVLC) system. In this paper, we experimentally demonstrate a S2SVLC system based on VLC technology using a smartphone screen and a smartphone camera over a link span of 20 cms. We analyze the Lambertian order of the smartphone screen and carry out a channel characterization of a screen to camera link-based VLC system under specific test conditions.
