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
