Chaos communications - Principles, schemes, and system analysis

This paper provides a comprehensive overview of chaotic communication methods and schemes with emphasis on digital schemes. Starting from general demands for communications, the general communication system structure is introduced. From this basic viewpoint, different classical and chaotic modulation and demodulation methods are treated and classified, For the performance analysis and comparison, a discrete-time statistical calculus is developed and applied to chaotic signal processing schemes. Discrete-time baseband models are developed, which are suitable for a statistical performance analysis. Analysis results for various example systems are provided and compared. New decoder structures arc proposed and included in the comparative studies.
