DIT_FFT

这是一个matlab讲义，内容丰富，我发给了几个同学，都说不错。(err)

Linear algebra package

Mathematics concepts for electrical engineers

说明：  】利用混沌动力学系统中logistic 映射先对水印图像进行置乱预处理以增强其鲁棒性, 在小波域中将原始音频信号按比例分段, 此比例为原始音频信号低频部分与水印信号个数之比, 然后将水印信号加入到音频信号的 低频部分。用StirMark 攻击后的实验结果表明, 该算法对StirMark 的部分攻击具有一定的鲁棒性。(The logistic- map sequences to encrypt the watermark are used. The original audio signal in DWT (Discrete Wavelet Transform) domain is seperated into some pieces determined by the ratio between the length of the low frequency parts and the length of the encrypted watermark. Every bit of the watermark is added into the relevant pieces of the low frequency parts in the DWT domain. Experimental results show that the algorithm is robust against some StirMark attacks.)

这是对音频新训好进行bch编码后通过代同滤波器的程序(This is the new audio training for good after the BCH code generation through with the procedure Filter)

改进的EEMD程序，可弥补加噪去除不干净的问题(Improved EEMD procedures, can make up for the noise removal is not clean problem)

Matlab algorithm for Kmeans Simulation . It runs the Kmeans simulation using kmeans keyword. The files can be used for Points and Centroids

说明：  用simulink搭建的解耦前馈控制仿真系统(Simulation system of decoupling feedforward control based on Simulink)

比较均匀量化和A律13折线编码的信号量噪比，通过比较可以看出两者的区别。但不知道正不正确(A law more uniform quantitative and broken line 13 the amount of coded signal to noise ratio, can be seen by comparing the difference between the two. But do not know is not correct)

说明：  《面向matlab工具箱的神经网络理论与应用》配套源程序，非常的不错("Matlab Toolbox for the neural network theory and application of" complementary source, very good)
