Chaos-Shift-Keying Secure Digital Communications Using Feedback to Synchronize Chua's Circuit

摘要

In this paper, a chaotic secure communication system using a feedback controlling subsystem is presented. The transmitter and the receiver are built with Chua's circuits. We find that, using feedback controlling, the time for the receiver to obtain the synchronization with the transmitter can be obviously decreased. The correlation between the time and the feedback coefficient is presented at the end of this paper.
