摘 要：In chaos-based communications, it is essential to know and to control the spectral features of the chaotic signals to be transmitted, since every communication channel is bandlimited to some extent. In this chapter, we review a proposal of discrete-time communication system using chaotic synchronization in which the spectrum of the transmitted signals can be moderately shaped. Numerical studies on the Lyapunov exponents of the generated signals are presented and related to the performance of this chaotic communication system.
