C-OOK Code

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, which was just recently released in April 2019.

The C-OOK Code project is cleaned, well-packed and documented.

IMPORTANT NOTICE: We have recently release the update of C-OOK (April 2020 version). The document reviewing the newest Software User Interfaces is now available at:

Technical features of the code project

Our C-OOK code project is deployed following the release technical specification of C-OOK in the IEEE 802.15.7-2018 standard.

We provide three-in-one package:

  1. C-OOK Tx-Rx back-to-back package: which is a full system simulation in LabVIEW. Users can run the package without the requirement of hardware.
  2. C-OOK BER versus SNR back-to-back package: which gives the simulation of C-OOK system under AWGN and the simulation of C-OOK system implemented with different bit detection methods.
  3. C-OOK Tx-Rx package for optical link (hardware required): which can be used for different types of LEDs and rolling shutter camera.

All these three packets will be delivered to you to test both cases: back-to-back link (or simulation mode), and the practical optical link. From a single time delivery, multi-benefits you will earn.

Some interesting technical features:

  1. Multi-tasking and pipeline techniques for real-time image processing
  2. Use-defined region-of-interest to extract data from light source(s)
  3. Re-configurable modulation and demodulation process
  4. All you-need-to-know about four OOK-modes within IEEE 802.15.7-2018 standard
  5. Real-time data display and BER monitoring
