摘要：

This paper examines the design of a prototype of a single cell three-channel visible light communication (VLC) based on wavelength division multiplexing for a radio frequency (RF)-free indoor healthcare. For a low complexity application, a single red green blue (RGB)-type white light-emitting diode (LED) and a single color sensor are adopted. An active low pass filter is utilized for robust light detection to eliminate ambient light and low frequency noise. The incoming tri-color lights are separated by an adopted color sensor and simultaneously demodulated by a receiver processor. Then, the collected data are monitored in real-time and analyzed to provide the necessary medical attention to the concerned patient. (C) 2017 Optical Society of America
