Abstract

This paper proposes a new digital communication scheme, which uses chaotic signals based on the adaptive synchronization and parameter identification technique of chaotic systems reported recently. Due to the multi signal character, this scheme combines the chaotic signal transmission with the MIMO channel technique in a wireless environment, which is different from the traditional chaotic communication frameworks. From a practical perspective, an outline of modulation, channel model, demodulation and non-coherent detection is investigated. Furthermore, system performance is evaluated by simulations, and improvements on this scheme are also discussed.
