Should Analogue Pre-Equalisers be Avoided in VLC Systems?
TL;DR: It is shown by means of theoretical and experimental investigation that VLC with multi-band carrierless amplitude and phase modulation with bit-loading can outperform V LC with analogue pre-equalisers.

TL;DR: It is shown that, the electrical parasitics in the chip and packaging introduce significant attenuation beyond a resonance frequcency, so care should be taken when designing high-speed driver and/or equalization circuits for VLC systems.
Visible light communications: increasing data rates with polarization division multiplexing.
Petr Chvojka,Andrew Burton,Petr Pesek,Xicong Li,Zabih Ghassemlooy,Stanislav Zvanovec,Paul Anthony Haigh +6 more
TL;DR: A new configuration for visible light communication systems, which results in doubling of the data rate due to the use of polarization division multiplexing and for the first time, it is shown that it is possible to transmit and successfully recover two separate orthogonal frequency divisionMultiplexing signals on each polarization.

An Equivalent Circuit Model of a Commercial LED With an ESD Protection Component for VLC
TL;DR: An equivalent circuit model for a typical commercial light-emitting diode (LED) used in visible light communication (VLC) applications is proposed in this paper, where the parameters of the elements in the model are extracted from the measured impedance using a vector network analyser.

A 40 Mb/s VLC System Reusing an Existing Large LED Panel in an Indoor Office Environment.
TL;DR: In this paper, the authors investigated the feasibility of adding data communication functionality to the existing lighting infrastructure by designing an experimental system in an indoor environment based on an off-the-shelf LED panel typically used in office environments.
