摘要： 从矢量空间基函数的角度阐述了具有限制反馈的自适应IR滤波器——Laguere滤波器和Gamma滤波器,提出了这类滤波器的统一模型.在此基础上,对其性能作了较为详细的分析与比较,指出一般意义上Gamma滤波器性能好于Laguerre滤波器,导出了具有限制反馈的自适应ⅡR滤波器的Wiener-Hopf方程及其相应的LMS算法,并给出了仿真结果.

Abstract: We present a new approach using vector space base functions to discuss the adaptive ⅡR filter with restricted feedback——Gamma filter and Laguerre filter, and propose a unified model for them. We analyze and compare this class of filters in detail, showing that Gamma filter has advantages over Laguerre filter. We also derive the Wiener-Hopf equation and the corresponding LMS algorithm of them. Some simulation results are also presented.
