自适应Volterra滤波器的递归结构和类递归结构及其算法和应用

本文参考自适应IIR滤波器理论,提出了自适应Volterra滤波器(AVF)的递归结构和类递归结构,讨论了其特点和应用范围.递归结构的引入可显著减少AVF的参数和计算量.本文还给出了类递归结构AVF的在线辨识算法和在非线性系统辨识中的应用;给出了递归结构AVF的滤波算法和在非线性相关噪声抵消中的应用.在仿真实验中,将上述算法与多层感知器和非递归结构AVF做了对比.结果表明,本文算法住性能和计算量上均有明显优势。

RECURSIVE STRUCTURE AND QUASI-RECURSIVE STRUCTURE OF ADAPTIVE VOLTERRA FILTER AND THEIR ALGORITHMS AND APPLICATIONS

The recursive structure and quasi-recursive structure of Adaptive Volterra Fil-ter(AVF) are put forward, their algorithms are given, and their characteristics and applications are discussed. The introduction of recursive structure can remarkably reduce the parameters and computational cost of AVF.
