This study introduces a theory for chaos-based communication, defining dynamical channel capacity. It quantifies how much information a dynamical system can transmit, considering its generated information.

Area of Science:

  • Information Theory
  • Dynamical Systems
  • Communication Systems

Background:

  • Chaos theory offers unique properties for secure and efficient communication.
  • Characterizing information transmission in chaotic systems is crucial for practical applications.
  • Existing models may not fully capture the information-generating nature of dynamical systems.

Purpose of the Study:

  • To establish fundamental principles for a theory of chaos-based communication.
  • To define and quantify the 'dynamical channel capacity' of a system.
  • To account for the information generated by the dynamical system itself in capacity calculations.

Main Methods:

  • Developing a theoretical framework for chaos-based communication.
  • Defining the concept of dynamical channel capacity.
