Abstract :
Using the property that chaotic systems are sensitive to system parameters, an adaptive chaotic digital encoder with variable parameters is proposed which can jump among different chaotic systems at different times. More complexity and much better correlation properties can be achieved to meet secure communication applications. Simulation results and a comparison between the new one and Frey´s adaptive chaotic digital encoder are also given, showing the performance of the new encoder
