matlab数学手册，里面是这本书的word文件和源代码(Matlab mathematics is the book handbook, the word document and the source code)

simple function to test watermarking

这是一个信道盲均衡的程序，程序若然简单，单是非常经典好用。(This is a blind channel equalization program, the program and if so simple, one is very classic easy to use.)

说明：  这里介绍了一种基于自适应滤波的噪声抵消法，采用归一化最小均方误差算法，采集实际噪声环境下各种不同信噪比的带噪语音样本进行降噪处理，实验结果表明，处理后信号的信噪比得到了较大程度的提高，大大改善了听音效果，具有很高的可懂度，且语音自然度好，没有失真；并与谱减法进行了比较，自适应噪声抵消法的降噪幅度比谱减法有一定提高，在听音效果上，用自适应噪声抵消法处理后的语音在清晰度，自然度方面优于谱减法。(Here a novel adaptive noise cancellation method using normalized least mean square algorithm, collecting a variety of actual noise environment, the SNR of noisy speech samples for noise reduction, experimental results show that treatment After the signal to noise ratio was greater improvement in the level, greatly improved the listening results, with high intelligibility and naturalness of speech is good, no distortion and were compared with the spectral subtraction, adaptive noise cancellation law than the spectral subtraction noise reduction rate of a certain improvement in the listening results, and with the adaptive noise cancellation method in the treatment of voice clarity, naturalness is better than spectral subtraction.)

决策树源代码，用matlab语言编写的，适用于分类及相关问题的分析(Decision tree source code, written with matlab language, suitable for classification and analysis of the related problem)

OFDM的simulink仿真，希望对筒子们有帮助(OFDM-simulink simulation, and they hope to have the cheese to help)

这是一个用MATLAB编的免疫克隆算法优化函数的程序，免疫克隆算法是一种比较新的有效的优化算法，近两年对他的研究很多。(Artificial Immune)
