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
