Chaotic systems are deterministic non-linear dynamical systems which have intrinsic properties such as: irregularity, aperiodicity, and are impossible to predict over long periods of time. Cognitive radio on the other hand, has emerged recently as a powerful means to tackle the spectrum congestion problem. The goal of this thesis is to combine the benefits of the chaos communication system with the cognitive radio to create a robust, highly secure, flexible chaotic cognitive radio system. We first begin with a short survey of chaotic communication and cognitive radio technology. Then we compare chaotic waveforms to other conventional PN sequences and show its superiority in security and multiuser capabilities. We then propose a novel frequency domain based chaos communication system that is capable of operating over multiple non-contiguous frequency bands. Furthermore, we analyze the performance of this system in different channel models and in multiuser scenarios. Finally, we implement carrier-interferometry sequences along with the chaos sequence to increase the security and performance of the system.
