Performance enhancement of optical camera communication system using optical camera communication coding and region‐of‐interest detection [PDF]
IET Optoelectronics, 2021 Abstract Optical camera communication (OCC) is considered an important transmission scheme in implementing indoor navigation, beacons, and other Internet of Things applications. One of the disadvantages of OCC, however, is that transmission is successful only if the line‐of‐sight requirement is satisfied between transmitting LED lamps

Optical camera communications link using an LED-coupled illuminating optical fiber [PDF]
Optics Letters, 2021 In this Letter, we propose and demonstrate a novel wireless communications link using an illuminating optical fiber as a transmitter (Tx) in optical camera communications. We demonstrate an indoor proof-of-concept system using an illuminating plastic optical fiber coupled with a light-emitting diode and a commercial camera as the Tx and the receiver ...

Optical Lensless-Camera Communications Aided by Neural Network
Applied Sciences, 2019 Currently, the optical components of a camera embedded in the device constrain its overall thickness. Moreover, if the camera is strongly shaken, the lens and sensor may be misaligned, resulting in a defocusing effect.
