Cooperative Visible Light Communications With Full-Duplex Relaying

IEEE Photonics Journal, 2017
In this paper, we investigate cooperative visible light communication (VLC) system where an intermediate light source acts as a relay terminal. We assume that relay terminal operates in full-duplex mode.

Ultrasensitive bionic photonic-electronic skin with wide red-shift mechanochromic response

Light: Advanced Manufacturing
Mimicking animal skin is an effective strategy for enhancing the performance of artificial skin. Inspired by a chameleon’s iridophore and a spider’s slit organ, a novel photonic-electronic skin (PE-skin) with excellent optical/electrical dual-sensing ...

Indoor visible light communications: performance evaluation and optimization

EURASIP Journal on Wireless Communications and Networking, 2018
For indoor visible light communication (VLC), much work has been done when the noise is independent of the input signal. However, less effort is made when the VLC system suffers from the input-dependent noise.
