Synchronization of Discrete-Time Chaotic Systems in Bandlimited Channels

الملخص EN

Over the last couple of decades, many methods for synchronizing chaotic systems have been proposed with communications applications in view.

Yet their performance has proved disappointing in face of the nonideal character of usual channels linking transmitter and receiver, that is, due to both noise and signal propagation distortion.

Here we consider a discrete-time master-slave system that synchronizes despite channel bandwidth limitations and an allied communication system.

Synchronization is achieved introducing a digital filter that limits the spectral content of the feedback loop responsible for producing the transmitted signal.
