Chaotic Signal Design with Selected Parameters

Abstract

Chaotic signal is very important for chaotic communication and chaotic encryption. In his paper a method of producing chaotic signals with arbitrary magnitude and spectrum is presented, which is based on the Lorentz system by introducing some parameters of the system to realize the selected magnitude and spectrum. Furthermore, the validity of this method by theory and simulation is shown. In addition, this kind of generators is easily implemented, and the signal is suitable for protecting the information in communication systems.
