摘要
提出一个通过混沌同步实现保密通信的新方法。用变型蔡氏电路为例,数值模拟证明了这个方法是非常成功的。它的优点是信息信号能够和混沌载波信号一样大,因此当仅发射一个信号时也能达到很高的信噪比,并实现极好的混沌同步与高保真的信号恢复。
This paper puts foward a novel way to achieve chaotic synchronization. Take the modified Chua's circuit as example, the numerical simulation shows this way is very successful. The message signal can be as large as the chaotic carrier signal, so the signal-to-noise ratio can be very high even when only one signal is transmitted. The synchronization is excellent and the retrieved signal is virtually perfect.
