在信道均衡运用中，将发送的受信道失真影响的原始信号作为自适应滤波器的输入信号，可期望信号是原始信号的时延形式，如图22（a）所示。通常情况下，输入信号的时延形式在接收端是可以得到的，采用形式是标准的训练信号。当MSE达到最小时，就表明自适应滤波器代表了信道的逆模型（均衡器）。(In the use of channel equalization, will be sent by the effects of channel distortion signal as the original adaptive filter input signal, can expect signal is the original signal delay form, Figure 22 (a) as shown. Under normal circumstances, the input signal at the receiving end delay form is accessible, using the form of training is a standard signal. When the MSE to achieve the best hours, show that the adaptive filter on the channel represents the inverse model (EQ).)

这是机械工业张德丰《MATLAB与外部程序接口编程》随书源码，这本书详细介绍了MATLAB与C、C++、Excel、VB、Delphi、FORTRAN相互调用的方法，使得我们可以综合利用传统编程语言执行效率高和MATLAB函数库功能强大的优势，本书对于MEX和MAT文件、MATLAB引擎、MATLAB C/C++函数库、Matcom等都作了详细的介绍并举例说明，书籍最后还介绍了MATLAB的串口接口。(This is the machine-building industry张德丰" MATLAB and external program interface programming" with the source book, this book details MATLAB with C, C++, Excel, VB, Delphi, FORTRAN calls each method, allows us to provision of comprehensive utilization of traditional efficient way to implement the language and MATLAB function library powerful advantages, this book MEX and MAT files for, MATLAB engine, MATLAB C/C++ function library, Matcom have made a detailed introduction and examples, the book also introduced the final MATLAB serial interface.)

Matlab+常用图像函数,包括图像的读写,显示,模拟噪声生成函数等(Matlab+ common image functions, including reading and writing images, display, analog functions, such as noise generated)

pitch 的相关程序，自己编写的，可以条用，很好的，赶快下吧(pitch of the relevant procedures, their preparation, can be used, very good, quickly, are you)

高速跳频，调制样式为DPSK(DPSK/FH)，包括信号的发射接收模型，自己写的代码，仅供参考。(High-speed frequency hopping, modulation pattern for DPSK (DPSK/FH), including the launch of signal reception model, write your own code, for reference purposes only.)

利用matlab仿真金属圆柱体内电磁波分布，有助于掌握电磁波的传播情况。 把程序文档放入matlab的默认读取文档中，打开Cwave.m。Cwave.m是演示程序，由它调用其它函数。其中Z表示Kz*z，范围为0~2*pi。默认取2*pi为一个周期，num表示在一个周期内平均取多少个Kz*z值，默认为50(计算后每个值如Er都有五十幅图)。CWaveGuideCaculate函数用于计算Er,Efia,Hr,Hfia,Hz等值。CWaveGuideShow用于三维显示计算后得到的值，可以比较生动看到在一个周期内计算量的一连串的变换。(Matlab simulation using electromagnetic wave distribution inside the metal cylinder, is useful in the propagation of electromagnetic waves. To process the document read into matlab' s default document, open the Cwave.m. Cwave.m is the demonstration program, which will call other functions. Where Z said Kz* z, the range of 0 ~ 2* pi. The default access for a period of 2* pi, num, said the average take in a cycle number of Kz* z, default is 50 (calculated as per the value of Er has 50 chart). CWaveGuideCaculate function is used to calculate Er, Efia, Hr, Hfia, Hz equivalent. CWaveGuideShow been calculated for three-dimensional display of values, can be seen more vividly in a cycle of computation of a series of transformations.)

本程序实现了matlab自带函数imfillter的功能，是.m文件的形式，参数和imfilter一样可选。程序附有图片，并且在程序最后使用imfilter，便于直接对比观察处理效果。注：本程序是读入RGB图像，转换成灰度图进行处理。(This program implements the function of matlab own function imfillter is. M file in the form of the same parameters and imfilter optional. Procedures with pictures, and last used in the program imfilter, for direct observation of treatment effect contrast. Note: This program is read into the RGB image into grayscale processing.)
