Chaotic communication using Pecora Carroll complete replacement and parameter modulation without controller

Abstract

This work presents chaos synchronization and parameter adaptation using P-C complete replacement scheme. Finally this scheme is applied to secure communication. The advantage of proposed scheme is shown based on the fact that there is no need for controller at the receiver side which is the basic requirement in most of the existing chaotic communication schemes. Only coupling is sufficient to achieve secure transmission of information signal. The basic approach of this synchronization scheme is that switching time is less than average time period of choosen transmitter. Numerical simulation results verify the robustness of the proposed scheme.

“…Wireless chaotic communication has many features other than the systems dependent on a classical harmonic signal, viz enormous safety and hide information advantages [22], weak power spectrum intensity, resistance to multipath fading, is simply implemented for broadband communication system [23], and sensitivity to initial conditions [8,[24][25][26][27]. Pecora and Carroll described that Chaotic systems can to synchronization and can be implemented utilized electronic circuits [28].…”
