Engineering chaos cognitive radio Chaotic systems are deterministic non-linear dynamical systems which have intrinsicproperties such as: irregularity, aperiodicity, and are impossible to predict over long periodsof time. Cognitive radio on the other hand, has emerged recently as a powerful meansto tackle the spectrum congestion problem. The goal of this thesis is to combine the benefitsof the chaos communication system with the cognitive radio to create a robust, highlysecure, flexible chaotic cognitive radio system. We first begin with a short survey of chaoticcommunication and cognitive radio technology. Then we compare chaotic waveforms toother conventional PN sequences and show its superiority in security and multiuser capabilities.We then propose a novel frequency domain based chaos communication systemthat is capable of operating over multiple non-contiguous frequency bands. Furthermore,we analyze the performance of this system in different channel models and in multiuserscenarios. Finally, we implement carrier-interferometry sequences along with the chaossequence to increase the security and performance of the system. 2010-07-12 English text Wright State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=wright1278613042 http://rave.ohiolink.edu/etdc/view?acc_num=wright1278613042 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
