说明：  基于matlab开发平台的决策树的实现，该算法比较精良容易懂。(the realization of decision tree：Implementation of decision tree based on MATLAB development platform, the algorithm is relatively good )

说明：  采用小波包变换去除脉搏波的基线漂移和公平干扰 效果较小波变换更好(Wavelet packet transform to remove baseline drift and pulse wave interference effect of smaller transform fair better)

用matlab 实现各种算法，如burg算法，LMS算法，比较基础，适合初学者。(Using matlab implementation of various algorithms, such as burg algorithm, LMS algorithm, a comparative basis, suitable for beginners.)

对暂态信号进行EMD分解，得到边际谱。具体如何运行，文件夹里面都有。(EMD decomposition of the transient signals, to obtain marginal spectrum. Specifically, how to run, which has folder.)

Matlab小问题 问: Matlab仿真中怎样编辑Scope中的图象??? 答: 实现的方法有以下的几种: 1）PrintScreen，然后粘贴到Windows位图编辑器，选择图像点击右键，选择“反色”即可； 2）在Scope中，它的参数设置的第二页，有一个Save Data to Workplace，将它选中，然后在下面的方框 中指定变量名，然后用plot命令画出； 3）直接在模型上再加一个，to Workplace模块，也用plot画出； 4) 等scope显示出来图像以后，在matlab上运行 set(0, ShowHiddenHandles , On ) set(gcf, menubar , figure ) 这时候你会发现scope的工具栏的上面多了一行，点击insert-axes，鼠标会变成十字形状，然后再图像的任意一处双击左键出现一个对话框PropertyEditor，选中style在窗口的右便会出现color，这时你就可以任意修改背景颜色了。 问: 怎样进行S-function的编程和使用??? 答: S-function也就是System-function的缩写。说得简单，S-function就是用MATLAB所提供的模型不能完全满足用户，而提供给用户自己编写程序来满足自己要求模型的接口。要了(err)

QPSK调制后产生QPSK信号，QPSK信号分别通过AWGN信道、Rayleigh衰减信道和Rician衰减信道，分别通过QPSK解调出数字信号，通过输入与输出数字信号的对比计算出仿真过程中的传输误比率，并将其与各衰减信道的理论误比率进行对比(Generate QPSK signal QPSK modulation, QPSK signals through AWGN channel, Rayleigh fading channel and Rician fading channel, respectively, through the QPSK demodulation of digital signals by comparing input and output digital signals to calculate the simulation process of transmission error rate, and to compare with the theoretical error rate for each decay channel)
