对于初学者具有参考意义，有较好的参考价值，包含特征值与特征向量的提取、训练样本以及最后的识别，表示出两帧图像间各个像素点的相对情况，对HARQ系统的吞吐量分析，多目标跟踪的粒子滤波器。

2FSK的调制解调，基于simulink的仿真(2FSK-simulink)

LMS自适应算法，对不同信道参数进行仿真，并输出计算结果(LMS adaptive algorithm, for different channel simulation parameters and output results)

ISAR的短时傅立叶变换程序，用于ISAR成像时的频率估计(ISAR the short-time Fourier transform procedures, ISAR imaging for the estimated frequency)

利用构造函数法和线性回归算求一一维微观形貌的分形维数可直接使用。 (The constructor method and linear regression operator seeking the eleven-dimensional morphology of the fractal dimension can be used directly.)

多元回归，利用matlab通过数据的大致分布，求得相应的函数表达式。(finding the function through datas by Matlab )

基于DFT的信道估计技术能提高ls或MMSE信道估计的性能，这种技术通过消除噪声来实现性能的提高。运用MATlab内部的高斯随机数生成器randn来生成信道，所以每次运行的程序信道会有所不同。

里面包含主元分析PCA的Matlab代码，包括提取主元，求方差贡献率，绘制贡献率直方图等(Which contains the principal component analysis PCA of the Matlab code, including the extraction of the main element, seeking variance contribution rate, contribution rate of histogram mapping, etc.)

利用转换公式将真彩图像转换为灰度图像。将灰度图像的每一个像素点对应一个元素保存在一个矩阵中。然后利用帧差法进行图像差分处理，从而提取出运动目标。对差分后的图像二值化处理，用最大类间方差分割法遍历求取最优阈值。使其作为基准，区分差分图像的背景元素和目标元素。最后用matlab进行编程使目标信息高亮显示在屏幕上。(The true color image is converted to gray image by transformation formula. Each pixel of a grayscale image is stored in a matrix corresponding to one element. Then the frame difference method is applied to image difference processing to extract moving targets. After the two valued processing of the differential image, the optimal threshold is obtained by traversing the maximum variance between classes. It is used as a benchmark to distinguish the background and target elements of the differential image. Finally, Matlab is programmed to highlight the target information on the screen.)

说明：  matlab程序，使用小波进行7层分解，选用软阈值函数(Matlab program, using wavelet for 7-level decomposition, using soft threshold function)
