摘　　要：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 order to better estimate the bifurcation parameter of the chaotic system, performance of adaptive filter based on paper [4] is investigated in this paper, and an error is corrected at the same the. Simulation results show that the adaptive filter can make chaotic Series converge quickly, and overcomes the limitation that the transmitted signal should be show-varying, which is quired by other chaotic control methods.
