此函数用于IS-95前向链路系统的仿真，包括扩频调制，匹配滤波，RAKE接收等相关通信模块。仿真环境: 加性高斯白噪声信道. 数据速率 = 9600 KBps (This function is used for IS-95 forward link system simulation, including the spread spectrum modulation, matched filter, RAKE receiver and other related communication module. Simulation environment: additive white Gaussian noise channel. Data rate = 9600 KBps)

基于D-J阈值的加性白噪声方差估计,两种算法的比较(D-J，noise,evaluation)

系统辨识里面的梯度校正参数辨识方法，实用的系统辨识算法(System identification inside the gradient correction parameter identification methods, practical system identification algorithm)

本代码经本人多次调试运行过，绝对可用。用户可根据（执行步骤）这一文件来运行程序。(After I debug this code to run over several times, absolutely free. Users can (step) of the file to run the program.)

苹果特征提取，按照灰度化，直方图均衡化，中值滤波，边缘检测，特征提取的顺序来 特征提取中，取得“比例系数”时，选择一张横径图片，序号与之前选择图像的相同(Apple feature extraction, according to grayscale, histogram equalization, median filtering, edge detection, feature extraction feature extraction in order to obtain " scale factor" , select a diameter of pictures, serial number and select the image before the same)

说明：  使用matlab的simulink进行仿真GMSK，并画出仿真图。(GMSK is simulated with Simulink of matlab, and the simulation diagram is drawn.)

说明：  该程序可以求得任意两个长度相同的离散信号的互相关系数以及自相关系数，并绘制其图像(The program can get the cross-correlation coefficient of any two discrete signals with the same length, and draw the image of the cross-correlation coefficient)

emd用MATLAB编程，用幻灯片演示，很形象直观(emd MATLAB programming, using slide shows, a very visual image)
