在混沌参数调制技术中，为了有效地提取混沌系统参数，本文在文献［４］的基础上，对自适应滤波算法的性能进行了仿真研究，并修正了其中的错误．仿真结果表明自适应滤波技术能够快速收敛，并能克服其它混沌控制技术中只对慢变信号有效这一局限性．
In the chaotic parameter modulation technique, in order to extract the chaotic system parameters effectively, this paper simulates the performance of the adaptive filtering algorithm based on the literature [4], and fixes the errors. The simulation results show that the adaptive filtering technique can converge quickly and overcome the limitation that other chaos control techniques are effective only for slowly changing signals.
