摘要/Abstract

摘要： 传统自适应滤波器的研究大多局限于Matlab、Simulink等工具，由于不能设计成一个虚拟仪器或者一个应用系统，无法测试滤波器在工程应用中的实际性能.因此，该文以LMS算法为例，设计了一种基于LabVIEW的LMS自适应滤波器.实验证明，该滤波器有效、性能良好，而且能很好地应用于语音信号的分析和处理.

Abstract: As traditional tools such as Matlab and Simulink are inconvenient to produce application systems, we propose to use LabVIEW to develop adaptive filters based on an LMS algorithm. Experiments show that the obtained filter is valid and has good performance in speech processing.

Key words: adaptive filter, LabVIEW, LMS algorithm, speech processing
