The development and application of white light‐emitting diode (WLED) lighting technology
are of great significance for reducing energy consumption. Commonly used WLED devices …

In this paper, we introduce the Matrix‐MMC propagation model for indoor wireless optical
channels. This proposed method is evolved from the modified Monte Carlo (MMC)–based …

In this paper, we present an indoor positioning system were trichromatic white LEDs are
used both for illumination proposes and as transmitters, and an MUX/DEMUX device, based …

Oxygen saturation levels in blood are usually measured with photoplethysmography (PPG)
using two LEDs, one in the red and the other in the near infrared region of the spectrum. A …

Indoor navigation is hardly managed by the usual Global Positioning System (GPS) due to
the strong attenuation of signals inside the buildings. Alternative based on RF optical …

En los últimos años, los sistemas de posicionamiento a nivel de interiores basados en la
tecnología de comunicación por luz visible usando diodos emisores de luz (LED-light …

Visible Light Communication (VLC) is currently a research topic due to the possibility to
handle the general, worldwide demanding need for communication. VLC uses Light Emitting …

Global Positioning System (GPS) cannot manage indoor positioning because the strong
attenuation of the signal by walls and infrastructures results in a lack of signal or poor …

An indoor positioning system where trichromatic white Light Emitting Diodes (LEDs) are
used both for illumination proposes and as transmitters and an optical processor, based on …

An indoor positioning system were trichromatic white LEDs are used both for illumination
proposes and as transmitters and an optical processor, based on a-SiC: H technology, as …
