Audio Watermark coding

说明：  PAM调制，实现模拟信号的数字抽样，能够启发matlab初学者的编程(PAM modulation, realize simulation signal digital sampling )

DES算法的加解密程序，MATLAB实现，还有实验报告一并附上。(DES algorithm encryption and decryption procedures, MATLAB implementation, the key length can only be eight.)

independente component analysis

主要是BURG法对声信号进行谱估计的程序。 还有利用BURG法求AR模型系数(BURG mainly on the sound signal spectral estimation process. BURG method are the use of AR model coefficients)

qpsk调制解调，外加取样判决脉冲成型，可以加入任何程序模块中，保证解码译码的便利性(qpsk modem, plus a sample sentence pulse shaping, you can add any program module to ensure ease of decoding decoding)

说明：  用基于下取样的技术easyensemble来实现类别不平衡数据的分类(Based on sampling techniques used under the category easyensemble to achieve the classification of unbalanced data)

分数阶傅立叶变换程序 Fractional Fourier Transform(Fractional Fourier Transform)

时间序列copula工具箱，包含密度函数，分布函数，对数似然函数等等，主要正对二元copula(This zip file contains a collection of Matlab functions for research on copulas for financial time series. Some simple example code is given in copula_example_code.m . A table of contents is given in contents.xls . Briefly, the toolbox contains CDFs, PDFs, log-likelihoods and random number generators for many common bivariate copulas, including the Clayton, Gumbel, Normal, Student s t, Frank, Plackett and symmetrised Joe-Clayton (SJC) copulas. Basic code for time-varying Normal, Gumbel and SJC copulas is included. )

BP神经网络算法，原数据与结果均已给出，望可以提供帮助(BP neural network algorithm, the original data and the results have been given, hope can help)
