Abstract
In chapters 3, 4 and 5 the phenomenon of chaotic synchronization has been studied. In this chapter, a popular application of chaotic synchronization in the area of secure communications is presented. Several chaotic communication systems with the receiver based on the chaotic synchronization concept are described. It is shown how a general approach to synchronization of chaotic flows via Lyapunov’s direct method and chaotic maps via the theorems of chapter 4 can be used for the development of chaotic communication systems. The communication schemes examined include those of chaotic masking, chaotic modulation and the newly developed chaotic communication scheme of initial condition modulation. Finally, the noise performance of the chaotic parameter modulation and the initial condition modulation are compared in terms of the bit error rate. It is shown that the newly developed initial condition modulation scheme outperforms the chaotic parameter modulation scheme.
