Since the early 1990s, a large number of chaos-based communication systems have been
proposed exploiting the properties of chaotic waveforms. The motivation lies in the …

In recent years, a large amount of work on chaos-based cryptosystems have been
published. However, many of the proposed schemes fail to explain or do not possess a …

We propose a new index-modulation-aided differential chaos shift keying (DCSK) system
using frequency-and-time resources, referred to as CTIM-DCSK system, to achieve high …

We present an improved and enlarged version of our book Nonlinear-namics of Chaotic and
Stochastic Systems published by Springer in 2002. Basically, the new edition of the book …

In the 1970's and 1980's, we saw phenomenal advancement in nonlinear science, which
had led to many important discoveries that greatly improve our understanding of the physical …

The statistical attributes of the received chaotic signal are evaluated in the noncoherent
chaos shift keying (CSK) modulation scheme in order to perform the demodulation. This …

This book deals with the bifurcation and chaotic aspects of damped and driven nonlinear
oscillators. The analytical and numerical aspects of the chaotic dynamics of these oscillators …

In this work, we present experimental results and SPICE simulations of chaos in a Colpitts
oscillator. We show that the nonlinear dynamics of this oscillator may be modeled by a third …

This paper deals with the problem of synchronization of a class of continuous-time chaotic
systems using the drive-response concept. An adaptive observer-based response system is …

A new noncoherent scheme called Permutation Index Differential Chaos Shift Keying (PI-
DCSK) modulation is proposed in this paper. This original design aims to enhance data …
