ML法能够很好的估计信号的信噪比,DC-DC部分采用定功率单环控制，代码里有很完整的注释和解释。( ML estimation method can be a good signal to noise ratio, DC-DC power single-part set-loop control, Code, there are very complete notes and explanation.)

说明：  编程计算图形的面积。程序可以计算圆形，长方形，正方形的面积，运行时先提示用户选择图形的类型，然后，对圆形要求用户输入半径值，对长方形要求用户输入长和宽的值，对正方形要求用户输入边长得值，计算出面积的值后将其显示出来。(Calculate the area of graphics programming. Program can calculate the round, rectangular, square area, run-time prompts the user to first select the type of graph, and then the radius of the circle requires the user to input the value of the rectangle requires the user to input the length and width values, requires the user to input side of the square grow the value to calculate the value of the area after the show.)

A PID controller coded in Matlab

一个matlabGUI程序，可以读取mat文件，并且对其中的信号叠加指定载波比的白噪声，并且绘图比较分析(A matlabGUI procedures, which can be read by mat paper, and one of the designated carrier signal superimposed over the white noise, and a comparative analysis of graphics)

这些文件夹里面包含着卷积码、调制、加高斯白噪声的程序、多径衰落径道的程序。。对那些初学者是很有帮助的。。。(The folder contains a convolutional coding, modulation, plus Gaussian white noise process, multi-path channel fading process. . Is very helpful for those beginners. . .)

本人自己做的功率谱估计的课程作业，利用matlab实现古典和现代功率谱估计，有间接法，burg法，music法。完全一步一步实现的，希望对大家有帮助(Course work, I do own the power spectrum estimation using matlab classical and modern power spectrum estimation, the indirect method, burg, law, music law. Full step by step, we hope to)

The advantage of static controllers is in their simple structure, however, their performance is not good. Therefore, in fact, the fundamental fuzzy controller is often combined with conventional ones (e.g., PID controller) to create a dynamic fuzzy controller to have higher control quality. there is an PIDFuzzycontroler example

录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；通过matlab界面进行编程设计，界面方便人们操作( Their record a voice signal, and recording the signal is sampled draw sample after the time-domain waveform and frequency spectrum of the speech signal designed by matlab programming interface, easy for people to interface)
