Introduction
On off keying (OOK) scheme is known as the simplest form of amplitude-
shift keying modulation by using two statuses: ON/OFF to transmit data
C-OOK stands for Camera- On Off Keying, a communication mode within
the IEEE 802.15.7-2018 Optical Wireless Communication standard.
Particularly, C-OOK is within the PHY V layer of IEEE 802.15.7-2018
standard.
MIMO C-OOK scheme, which updated the conventional C-OOK scheme,
used MIMO, region of interest, and match filter techniques
Introduction
The OCC system can easily deploy the MIMO technique. It can cope with
the big OCC problem of simultaneous connection with many light sources,
and it can make it feasible for the camera as well.
So the main goal of this contribution is to collect data from the multiple
transmitters and also enhance performance of existing OCC system such as
increase data rate, distance communication

camera on–off keying (MIMO–COOK) scheme.
Advantages of MIMO C-OOK scheme in
OCC system
Frame rate variation support. The sequence number (SN) allows the receivers to
decode data.
Improve system performance as compared with the conventional C-OOK due to
using a matched filter
Improve data rate: Due to using multi-LEDs, the data rate will be increased as
compared with the conventional C-OOK.
Improve the communication distance: by using the matched filter to detect the start
of frame and decode data, the communication distance is improved than the
conventional C-OOK.

This document explores the MIMO-COOK technique applied in the Optical Camera Communication (OCC) system to increase performance. The MIMO-COOK scheme captures data from multiple transmitters, improving data rate, distance communication, and system efficiency. With advantages like frame rate variation support and improved data rate through the use of multiple LEDs, this submission aims to enhance the existing OCC infrastructure.
