Recently, interest has turned to the mathematical concept of chaos as an explanation for a
variety of complex processes in nature. Chaotic systems, among other characteristics, can …

An overview over the methods currently under investigation for the transmission of
information hidden in a chaotic signal is given. First, the notion of synchronization is …

A circuit implementation of the chaotic Lorenz system is described. The chaotic behavior of
the circuit closely matches the results predicted by numerical experiments. Using the …

Describes a technique for transmitting digital information using a chaotic carrier. Each
symbol to be transmitted is coded as an attractor in Chua's circuit. The symbols are detected …

Secure communications via chaotic synchronization is experimentally demonstrated using
Chua's circuit. In our experiment the energy lost in the information-bearing signal is …

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 …

For Pt. I see ibid., vol. 40, no. 10, p. 640, 1993. Linear system-theory provides an inadequate
characterization of sustained oscillation in nature. This two-part exposition of oscillation in …

In this paper, we present a new method for the detection of signals in" noise", which is based
on the premise that the" noise" is chaotic with at least one positive Lyapunov exponent. The …

In this paper a systematic approach, based on the linear-state-observer design for
constructing two chaotically synchronized systems, is developed. The proposed method is …

This work tests the level of security in secure communication systems based on nonlinear
dynamics (NLD), or chaos. In these systems, a chaotic carrier signal is used in a type of …
