Simulation and Experimental Validation of Optical Camera Communication

TENCON 2024 - 2024 IEEE Region 10 Conference (TENCON)
While simulation tools for visible light communication (VLC) with photo detectors (PDs) have been widely investigated, similar tools for optical camera communication (OCC) with complementary metal oxide semiconductor (CMOS) sensors are lacking in this regard. Camera based VLC systems have much lower data rates owing to camera exposure times.
