摘要 根据IIR滤波器存在突出的缺点,对自适应IIR滤波器设计进行策略性研究。分别讨论输出误差法(OEM)和方程误差法(EEM)在设计自适应滤波器的应用。通过对仿真结果进行分析比较,修正的EEM克服OEM在设计结果中存在多个局部极小值的不足,优于OEM。从而提出设计自适应滤波器的策略和实现途径。 Aimed at disadvantage of IIR filer,design method for adaptive IIR filter was researched in detail. Output error method (OEM) and equation error method(EEM) was desired for adaptive IIR filter design. Comparison with OEM, improved EEM overcome the shortcoming of infinitesimal avalue in convergence.The simulation show that EEM outgo OEM, which provide an approach for design of adaptive IIR filter.
