Correlation-based receiver for optical camera communications
Optics Express, 2019 In color-multiplexed optical camera communications (OCC) systems, data acquisition is restricted by the image processing algorithm capability for fast source recognition, region-of-interest (ROI) detection and tracking, packet synchronization within ROI, estimation of inter-channel interference and threshold computation.

400 m rolling-shutter-based optical camera communications link [PDF]
Optics Letters, 2020 In this Letter, we develop a novel technique, to the best of our knowledge, to increase the link span ( L s ) of a rolling shutter (RS)-based optical camera communications (OCC) system by reducing the spatial bandwidth of the camera in the out-of-focus regions.

OCC-ID: New Broadcasting Service-Based Cloud Model and Image Sensor Communications
International Journal of Distributed Sensor Networks, 2016 In recent decades, the main data traffic of mobile communication is based on the RF technology. Even though the efficiency from optimization for utilization or reuse is applied, there is a limitation of increased traffic demand of RF communication ...
