A Sliding-Mode Adaptive Observer Chaotic Communication Scheme

In this paper, we present application of sliding-mode adaptive observer for state reconstruction of continuous-time nonlinear systems with uncertainties in a chaotic communication scheme. Using synchronization in conjunction with digital communication schemes, we have enhanced the security of the transmitted signal and achieved a satisfactory, typical, secure communication scheme. The proposed system requires only one observer, which is an advantage over some of related work in this area. The simulation results demonstrate the feasibility of this scheme.
