回波抵消器中常用的几种自适应滤波算法有LMS, NLMS, RLS等算法。对现有主要算法的性能进行了分析，并对优缺点进行评价和比较。为了在收敛速度和运算量之间得到很好的折衷，对NLMS算法改进，得到了 PNLMS(Echo cancellation devices commonly used in adaptive filtering algorithm has several LMS, NLMS, RLS, such as algorithms. The main algorithm of the existing performance analysis, and evaluation and comparison of the advantages and disadvantages. For the convergence between computing speed and a good compromise on the NLMS algorithm improvements have been PNLMS)

关于matlab的三角形线性单元的就算程序。适合初学者(Matlab triangle on the unit even if the linear program. Suitable for beginners)

这个程序可以自定义颜色选择框，因为matlab自带的uisetcolor在编译后的.exe中运行会导致窗口最小化，所以可以自定义颜色选择框(This procedure can customize the color selection box, because in uisetcolor built-in matlab compiled. Exe run will lead to minimized windows, so can customize the color selection box)

输入齿轮基本参数，绘制数字齿轮图形，并生成离散齿轮数据点坐标。(The basic parameters of the input gear, illustrated with digital gear graphics, and generate the coordinates of the discrete gear data points.)

说明：  Digital steganography

该程序可以实现对于信号的时域参数提取以及信号的包络分析(The program can realize time domain parameter extraction of signals and envelope analysis of signals)

learning the kalman filter (Matlab Code)(learning the Kalman filter (Matlab Code))

MATLAB的基本指令，通过这个可以更好的学习MATLAB的使用(MATLAB s basic instructions, this can be a better learning through the use of MATLAB)

统计一段文字中单词的数目，程序可运行，效果正确(The number of words in a text statistics, the program can be run, the effect is correct)

一个完整的HHT程序，需要先下载EMD工具箱(A complete HHT program, you need to download the EMD Toolbox)
