----------------------------------------------------------- CALL FOR PAPERS IEEE Transactions on Circuits and Systems-Part I Special Issue on: "APPLICATIONS OF CHAOS IN MODERN COMMUNICATION SYSTEMS" This Special Issue intends to address the growing role of nonlinear dynamics and chaos theory in modern communication systems. The focus is on those elements and/or algorithms in the transmitter-receiver chain which exploit properties of nonlinear systems and chaos. Chaotic signals are characterized by random-like behavior in the time domain, and by continuous broadband power spectrum in the frequency domain. These properties have emerged in several applications in the communication field. Chaos-based communications systems are now in a mature state of development and several possible schemes have been proposed and characterized. A crucial step towards the implementation of practical communication systems includes a good bit-error-rate (BER) performance in the presence of noise and distortion, resistance to multipath propagation, and multi-user capabilities. In these areas there has been recently a great research activity. The aim of this Special Issue is to identify those ideas which might lead to some real engineering applications. Original research and tutorial papers are solicited in the following areas: - Nonlinear circuits and systems for chaos-based communications - Chaos in information theory and processing: * Estimation of chaotic signals * Modeling with chaotic signals * Applications of symbolic dynamics * Noise filtering exploiting determinism - Chaos-based modulation techniques: * Chaotic pulse-position modulation * Self-synchronizing chaotic communication systems * Noncoherent chaos-based communication systems * Multiplexing and multiple-access techniques exploiting chaos - Spread-spectrum communications using chaos: * Direct-sequence spread-spectrum systems based on chaos * Chaos-based frequency hopping systems - Chaos and cryptography The Guest Editors for this Special Issue are: Dr. Ljupco Kocarev (kocarev@heisenberg.ucsd.edu) Dr. Gian Mario Maggio (gmaggio@ucsd.edu) Prof. Maciej Ogorzalek (maciej@zet.agh.edu.pl) Dr. Lou Pecora (pecora@anvil.nrl.navy.mil) Prof. Kung Yao (yao@ee.ucla.edu) Contributions for this Special Issue should be sent to: Dr. Lou Pecora Code 6340, Naval Research Laboratory Washington, D.C. 20375-5000 U.S.A.
