构造一组被噪声污染的方波或三角波数据，试选取适当的FIR滤波器结构和参数，分别应用LMS,DFT/LMS和DCT/LMS算法来实现自适应滤波器，对改组数据进行滤波，并分析仿真结果。-Construction Group was one of the Noise Pollution square or triangular wave data, Examination choose appropriate FIR filter structure and parameters, applicat

LMS是自适应滤波器设计中的一种算法，本文件为LMS算法在matlab中的应用。-LMS is the design of adaptive filter of an algorithm, this document is for the LMS algorithm in MATLAB application.
