Multispectral Optical camera communication links based on spectral signature multiplexing
IET Optoelectronics, Volume 17, Issue 4, Page 91-100, August 2023., 2023 This paper focuses on using the multispectral cameras' features to take advantage of the light‐emitting diode (LED) behaviour in a novel communication scheme based on spectral signature multiplexing. The thermally induced LED variations can be detected by the multispectral camera to obtain new communication channels from the same device.

A unilateral 3D indoor positioning system employing optical camera communications
IET Optoelectronics, Volume 17, Issue 4, Page 110-119, August 2023., 2023 This paper investigates the use of a visible light positioning system in an indoor environment to provide a three dimensional (3D) high‐accuracy solution. The proposed system can retrieve the 3D coordinate of the Rx using a combination of the angle of arrival and received signal strength (RSS).
