Herein, this thesis is constructed with two chapters representing two series of OCC systems. These OCC systems are designed to employ MIMO waveforms; among them, some are standardizing in the IEEE 802.15.7-2018 OWC standard (including A-QL for Screen OCC, and S2-PSK/ HS-PSK for V2X), some are pending for later IEEE 802.15 OWC contributions (including OFDM modulation formats). The thesis content is organized as two separate parts as follows:Part I introduces newly designed codes for optimal sequential transmission over the screen, being intended for short-range point-to-point communication. It commences with an ongoing-standardized color code design, known as an Asynchronous-Quick-Link (A-QL). This novel design is a complete version of screen code design and ready-implemented just like existing QR code. After that, it introduces another design of screen code with complex spatial OFDM series. From the concept and mathematical analysis to the experimental implementation and verification shall disclose notable contributions.Part II addresses the novel waveforms designed for a challenging channel condition as in vehicular OWC, being intended for long-range multi-point-to-multi-point communication. Inspiring by the camera multi-RoI mode which enables the smart feature to adapt its frame rate and achieve desired imaging quality, the RoI-signaling concept for the active communication link-setup is presented. Accordingly, the hybrid waveform designed for RoI-camera is uncovered. The detailed rule-of-thumb waveforms to compensate the environmental technical challenges, along with a variety of simulation results and implemental performance are thoroughly discussed.
