Chaotic channel coding, modulation,nonlinear observer-based synchronization, Lyapunovstability theorem.


In this paper, we present a chaotic channel coding and modulation scheme using nonlinear observer-based synchronization. In the proposed scheme, a Rossler -like system is used to generate analog patterns corresponding to the transmitted digital data in transmitter and a Rossler -observer is applied to decode these transmitted digital data in receiver. The synchronization between transmitter and receiver chaotic circuits can be guaranteed through Lyapunov stability theorem. Some simulation results are given to verify our works feasible.
