中值滤波 原图像画面清晰，添加了椒盐噪声以后图像上出现了明显噪声，经不同模板的中值滤波处理后图像上的噪声被虑去，但使得图像变得模糊，并且，使用的模板越大，去噪声效果越好，同时图像也越模糊。滤波效果明显优于平滑滤波。 (Median filtering the original image, a clear picture of the Salt and pepper noise added after the image there is a clear noise, and by different template after median filtering has been taking into account the noise on the image to go, but makes the image become blurred, and, using the template more large, to noise, the better the effect, while the more blurred the image. Filtering effect is superior to smoothing.)

说明：  matlab中plot函数用法，描述比较详细，只不过是pdf版本的(matlab_plot function usage)

说明：  可用于对原始离散信号的变分模态分解，实测有效(Used for variational mode decomposition of signals)

交互式选取生长起始点，将感兴趣部分分割出来。(Select starting point for interactive growth, will be interested in part from it.)

最基本的almouti空时编码程序，有需要的可以看看啊(the source for alamouti codes)

Lagrange Interpolation

％模拟偏微分方程kdv方程的水波。 ％通过修改已可以用来模拟其他的如KP方程等。( Simulation of partial differential equations of the wave KdV equation. By way of an amendment can be used to simulate the other, such as the KP equation.)

dtmf源代码，里面有信号产生，加噪，传输，接受，采样，判决等(Pages source code, with a signal generator, plus noise, transmission, acceptance sampling, judgments.)

LDPC encoding and decoding of rate 4/7

下垂控制，在微电网中有一定使用价值，是二级控制的下端(Droop control, there is a certain value in microgrid)
