Abstract

Chaotic digital encoders are enhanced to improve their complexity and correlation properties. A new adaptive chaotic encoder (ACE) is proposed which combines a chaotic encoder with an adaptive filter, producing a more complex and, potentially, more useful encoder. An inverse system approach is proposed that not only specifies the inverse of the ACE, but also shows an interesting way to understand synchronization in chaotic communications systems. Finally, simulation results are offered, showing the performance of the new encoder and synchronization of an IIR digital chaotic communications system
