Abstract

Chaos-based communication can be applied advantageously only if the property of chaotic systems is suitably exploited. Chaos communication has been studied for only a little more than a decade while traditional communication schemes have been developed for nearly a century. The hope was (and still is) that for some application chaotic communication will prove to be better than traditional communication. Yet, after one decade of research, in most cases chaos communication did not take the place of traditional communication schemes. As far as communication efficiency is concerned, chaotic communication schemes are typically less efficient than their traditional counterpart. Still, the main advantage of chaotic communication schemes is for analogy implementation of secure communication. In traditional communication schemes data has to be digitized before encryption takes place. This is due to the fact that traditional encryption is based on discrete number theory. In this paper we study the performance of Differential Chaos Shift Key (DCSK) modulation and we compare it to BPSK modulation, a new application of DCSK modulation is presented (transmission of the image).
