Design of MIMO C-OOK using Matched filter for Optical Camera Communication System

Currently, the wireless communication technologies are deployed commonly in many aspects such as Internet of Thing systems, eHealth systems, satellite communication system. Resides that. Radio frequency systems are emerged as the indispensable ingredients for almost the communication system However, , the effect of Radio Frequency with the human health are found by the researchers around the world. Example, the higher frequency will impact with human health is higher if the energy of signal exceeds the threshold. The Visible Light Waveform is researched to instead of Radio frequency band with three candidates: Visible Light Communication (VLC), Optical Camera Communication (OCC), and Light Fidelity (LiFi). In this paper. we overwiew the MIMO C-OOK modulation, that is upgraded from Camera On-Off Keying (one of scheme is applied in IEEE 802.15.7-2018 standard). with the matched filter technique in receiver side. the proposed scheme can improve the data rate and communication distance comparing with the conventional scheme.
