ABSTRACT

This chapter accesses the performance of a chaos-based digital communication system proposed in the literature under additive white Gaussian noise (AWGN). As the results are far from that obtained in conventional digital communication systems, review a way to increase robustness of chaotic synchronization using map lattices. It also evaluates the performance of a binary communication system using chaotic synchronization based on the one proposed in when the communication channel introduces AWGN. Chaos synchronization in a master-slave structure has been extensively studied as a model of the communication system, due to chaotic signals presenting sensitive dependence on initial conditions. Chaotic signals are deterministic, aperiodic, and sensitive to initial conditions. They are suited for use in applications that require security due to their difficulty of prediction and because they can be mistaken for noise in channel. In the last decades many works describing communication schemes based on chaotic signals have been published.
