Survey of indoor optical camera communication (OCC) systems for the Internet of lights
2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017In this paper, we propose the architecture and schemes of optical camera communication (OCC) system for the internet of lights (IoL) comprising an attentive indoor environment in which rolling-shutter cameras (including smartphone cameras) are used to receive data from light sources.

An indoor positioning method in a concert hall using optical camera communication (OCC) technology
2017 International Conference on Information and Communication Technology Convergence (ICTC), 2017Recent smart devices offer technologies that can measure indoor as well as outdoor locations. In the case of outdoor positioning, a global positioning system (GPS) is generally used. There is a limit to the method of using the GPS signal for indoor positioning.

Curved OLED-based NLOS optical camera communications links.
Applied Optics, 2023In this paper, for the first time, to the best of our knowledge, we experimentally demonstrate the use of a curved organic light emitting diode (OLED) as a transmitter (Tx) in the non-line-of-sight (NLOS) optical camera communication (OCC) link for an ...

Near-Infrared based Optical Camera Communications
International Symposium on Communication Systems, Networks and Digital Signal Processing, 2022We report, for the first time in the literature, an optical camera communications (OCC) link leveraging a near-infrared band at a wavelength of 850 nm that is visible to a standard camera and undetectable by the human eye.

OnionCode: Enabling Multi-priority Coding in LED-based Optical Camera Communications
IEEE Conference on Computer Communications, 2022Optical camera communication (OCC) has attracted increasing attention recently thanks to the wide usage of LED and high-resolution cameras. The lens-image sensor structure enables the camera distinguish light from various source, which is ideal for ...

Optics Letters, 2022
In this Letter, a sub-column pixel neural network (SCPNN) scheme is proposed to label the pixel patterns in modulation format shifting based optical camera communication (MFS-OCC) systems. The MFS scheme, by identifying on-off keying (OOK) and Manchester

International Symposium on Communication Systems, Networks and Digital Signal Processing, 2022
In this work, we propose a multiple inputs multiple outputs (MIMO) non-line-of-sight (NLOS) optical camera communication (OCC) system with multi-level pulse width modulation (MPWM) and difference-based pulse width recognition (DBPWR) schemes.

Towards Optical Camera Communications Using a Shape-tailored Illuminating Optical Fiber
International Symposium on Communication Systems, Networks and Digital Signal Processing, 2022We have recently presented a novel concept of optical camera communications (OCC) based on illuminating optical fibers (IOF) as transmitter (Tx). In this paper, we further investigate this concept of IOF-based OCC system by replacing a straight IOF by an
