A test for fractal boundaries based on the basin entropy
Andreu Puy, Alvar Daza, Alexandre Wagemakers +1
In dynamical systems, basins of attraction connect a given set of initial conditions in phase space to their asymptotic states. The basin entropy and related tools quantify the unp…
How to detect Wada Basins
Alexandre Wagemakers, Alvar Daza, Miguel A. F. Sanjuan
We present a review of the different techniques available to study a special kind of fractal basins of attraction known as Wada basins, which have the intriguing property of having…
Optimization of Chaos-based Coded Modulations for Compensation of Amplifier Nonlinearities
Francisco J. Escribano, José Sáez-Landete, Alexandre Wagemakers
In this work we expand the possibilities of a known class of chaos-based coded modulation (CCM) systems to address the problem of high-power amplifier (HPA) nonlinearity. The hypot…
A Spatial Time-Frequency Hopping Index Modulated Scheme in Turbulence-free Optical Wireless Communication Channels
Francisco J. Escribano, Alexandre Wagemakers, Georges Kaddoum +1
In this article, we propose an index modulation system suitable for optical communications, where the intensity of the light is modulated along the time, space and frequency dimens…
Chaos-Based Multicarrier VLC Modulator With Compensation of LED Nonlinearity
Francisco J. Escribano, José Sáez-Landete, Alexandre Wagemakers
The massive deployment of light-emitting diode (LED) lightning infrastructure has opened the opportunity to reuse it as visible light communication (VLC) to leverage the current RF…
Design and Performance Analysis of an Index Time Frequency Modulation Scheme for Optical Communications
Francisco J. Escribano, Alexandre Wagemakers, Georges Kaddoum +1
In this article, we propose an index modulation system suitable for optical communications, based on jointly driving the time and frequency of the signal: an index-time frequency h…
