传统PID的整定方法Z-N法，有助于大家快速整定参数，一起讨论哦(The traditional PID tuning method ZN method to help you quickly tuning parameters, and discuss Oh)

the comb pilot aided channel estimation in ofdm modulation is considered. the power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

此函数举例描述了一种实现CDF画图的方法，该方法简单易行(This function for example, describes an implementation of CDF drawing method is simple)

A set of functions to automatically process files saved by Avantes AvaSoft 7 software. See demo for example of use and descriptions within each m-file. The main function to use is avantesSpectrumRead, it will read all binary and ASCII files saved by Avantes within a directory. The binary file reader is the avantesBinaryRead function. A couple of additional useful functions (getScansByTime and getValueAtWavelength) are provided.

毕设题目，我用MATLAB程序编写的实现基于矢量量化的说话人识别系统，结合了qauflo算法。在给定的temp.wav录音文件的情况下，对不同的人的不同时间长度的语音进行辨识。实现与文本无关的自动说话人确认的实时识别。 使用步骤包括： 1 训练，2 tmgyCFR， 3 测试 4， 输出结果。 (Complete set topic, I use a program written in MATLAB-based VQ speaker recognition system, combining qauflo algorithms. In the case of a given temp.wav audio file, voice different people different lengths of time were identified. Real-time recognition and text-independent speaker verification automatically. Use steps include: 1 training, 2 tmgyCFR , 3 test 4, the output result. )

创建和编辑包 创建一个包需要指定： · 包的一个名字。 · 新包要求使用或链接的其他包的列表。 · 包编译时包含或绑定的单元文件的列表。包实质上是这些包含已编译.BPL功能的源代码单元的封装，包含（Contains）列表是想编译进包的定制组件的源代码单元放置的地方。一个包由C++源文件（.CPP）和扩展名为.BPK的工程选项文件定义。这些文件由包编辑器生成。 (Creating and editing package to create a package needs to be specified: a name of the package. The new package requires the use of or linked list of other packages. Compile a list of unit package that contains the file or binding. These packages contain essentially compiled. Source code package BPL unit functions, including (Contains) list is to source code modules compiled into the custom component package placed. A package of C++ source file (. CPP) and the extension. Engineering options file defines the BPK. These files are generated by the package editor.)

对一段振动信号emd分解后，求每个分量的峭度值，选取峭度最大的分量，求其包络谱，能够明显看出特征频率。(After a period of vibration signal emd decomposition, seeking kurtosis value of each component, the largest component of kurtosis, seeking its envelope spectrum, can obviously see that the characteristic frequency.)
