PAM-SCFDE for Optical Wireless Communications
Journal of Lightwave Technology, 2015 Multipath dispersion is a serious challenge in visible light communication (VLC) systems as these systems are used for indoor applications where there can be many reflections of the transmitted signal from the ceiling, walls, equipment, etc. These reflected signals cause intersymbol interference in the receiver and can degrade the performance of the ...

Advanced Science, EarlyView.This work demonstrates a receiver‐transmitter‐integrated metasurface that decomposes an incident wave into orthogonal components and routes them into separate channels. Inspired by a “Wheel‐of‐Fortune” mechanism, it enables independent control over the amplitude, phase, and polarization of the transmitted wave.
