Abstract

During the recent years, the application of chaotic systems and their signals have become a subject of intensive research. Researchers have made a great progress in the application of chaos in secure communication, associative memory, and optimum computation etc. In this paper we will use the `noise-like' property of chaos to generate broadband signals, that means we will treat chaos as the broadband sources. As we all know, we cannot distinguish chaos and noise only by their observable time series. The series of chaotic signals seem to be random and their spectrum is broad. So it inspires us to generate broadband signals through chaotic dynamics. The methods are various and they can be realized by hardware easily. The important thing must to be stressed is that we must decide which kind of method to be used due to the corresponding application. For example, in noise radar we need the noise signal to be modulated and transmitted, so the chaotic signal from the broadband source must have the best correlation property and distribution property etc. Use chaos to generate broadband signals is convenient, it is a new develop orientation in such field.
