Visible light communications: multi-band super-Nyquist CAP modulation
(Optical Society of America, 2019)
In this paper, we experimentally demonstrate the performance of a non-orthogonal multi-band super-Nyquist carrier-less amplitude and phase (m-SCAP) modulation for visible light communications (VLC). We break the orthogonality ...
Filter-less WDM for visible light communications using colored pulse amplitude modulation
(Optical Society of America, 2019)
This paper demonstrates, for the first time, a new wavelength-division multiplexing (WDM) scheme for visible light communications using multi-level coloured pulse amplitude modulation (M-CPAM). Unlike traditional WDM, no ...
Should Analogue Pre-Equalisers be Avoided in VLC Systems?
(IEEE, 2020)
Visible light communication (VLC) systems are highly constrained by the limited 3-dB bandwidth of light-emitting diodes (LEDs). Analogue pre-equalisers have been proposed to extend the LED's bandwidth at the cost of reduced ...
Demonstration of a Hybrid FSO/VLC Link for the Last Mile and Last Meter Networks
(IEEE, 2019)
In this paper, a hybrid free-space optical and visible light communication (FSO/VLC) system was experimentally demonstrated as a solution to overcome the last mile and last meter access networks bandwidth bottleneck. We ...
