Optical camera communication is foreseen to have an essential role in future systems requiring wireless communication capability. In this regard, high‐spectral‐resolution cameras, such as multispectral (MS) cameras, present specific characteristics that can be exploited to provide new features to optical camera communication links. Using the MS cam...
Optical camera communication (OCC) is a promising technology to be used in future wireless communication systems. In this work, a cluster-based data detection procedure is applied to enhance the performance of an OCC system. A multispectral camera is employed to capture the spectral variations in light-emitting diodes (LEDs) caused by temperature....
This work proposes using the changes in the LEDs’ spectral emission induced by temperature variations to implement emitters for new communication channels in Optical Camera Communication (OCC) systems. If a camera can discriminate the shift in LEDs’ spectral response, these modifications can be contemplated as a new data channel. The main advantage...
General-purpose Complementary Metal Oxide Semiconductor (CMOS) sensors perform the image desegregation in three channels (red, green, and blue) as a result of a band-pass wavelength filtering carried out using Foveon or Bayer filters. This characteristic can be used in Optical Camera Communication (OCC) systems for increasing the links’ data rate b...
Optical Camera Communication (OCC) applications have intensively risen in recent years. This work proposes using a multispectral or hyperspectral camera as an OCC receiver to take advantage of the high spectral resolution of this type of device with respect to conventional cameras. Furthermore, spectral features of the LEDs, usually used as transmi...
