October 2022 DCN 15-22-0552-00-007a Introduction 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. Rolling Shutter OFDM scheme was proposed to take advantage of OFDM waveform for high rate OCC system Hybrid waveform will be proposed by combining two waveforms: C-OOK and OFDM for Vehicular applications. With this scheme, two waveforms will be decoded with just one rolling shutter camera. Slide 3 Yeong Min Jang Submission
