Spread-Spectrum Communications Exploiting Chaos
Abstract
Our research into the uses of chaotic systems in spread-spectrum communications has resulted in many significant and important advances, which have been documented in 39 published papers. These advances were made in categories critical to the successful future incorporation of chaos in communication systems such as: carrier design, cryptographic security, synchronization schemes, robustness analysis, channel capacity, commercial applications, and practical synchronization in real-world wireless environments. Both theoretical and practical aspects were considered, for example: An integrated circuit capable of producing chaotic and hyperchaotic signals was fabricated; An important theory of generalized synchronization between different chaotic systems was developed; a new, improved synchronization scheme called impulsive synchronization was invented, which has lead to the filing of a patent; and a method based on adaptive control theory was developed to efficiently cope with parameter drift in practical chaotic circuits and time-varying channel distortion.
