保密通信中高速混沌键控技术的研究

Research on High Speed Chaotic Shift Keying Technology in Secure Communications

混沌保密通信是当今理论研究的热点之一,通过分析在非线形混沌系统中使用Hilbert变换产生相互正交的混沌序列,研究了一种高效的混沌差分键控通信系统,并推导出该系统的误码率性能公式。

Chaotic secure communications had b ecome one of the hot topics in recent y ears.In this paper,we make some research on quadr ature chaotic sequences,which are g enerated by Hilbert trans-form.Then we analyze a high -speed ch aotic differential chaos keying secure communications system.And we also analyze the performance o f this chaotic secure communication system.
