本程序是功率谱密度的仿真比较,关于三个信号源的具体情况参见《现代数字信号处理导论》上册，P202，习题5。 实验方法：周期图法、自相关法和协方差法。 (this procedure is the power spectral density of the simulation, 3 signal source on the specific circumstances, see the "modern digital signal processing" Introduction to the first volume, P202, Exercise 5. Experimental Methods : Chart cycle, since the correlation and covariance method.)

需要一个放有若干图片的文件夹，图片的文件名还需要提供一些信息，如“计61班.jpg”之类，具体格式可以修改源代码。然后显示图片让参与者猜是哪个班的。为系里男生节编写的一个简单的GUI程序(Need a put several pictures folder, pictures of the file name also need to provide some information, such as "(61 class. JPG," and so on, and the specific format can make changes to the source code. And then display picture participants had to guess which class is. For the day of a boy to write simple GUI program)

说明：  ORIGINAL MATGPR RELEASE

rayleigh fading channelmodel

语音信号的采集与处理，数字信号处理课设，数据模型归一化，模态振动，仿真效率很高的。( Acquisition and Processing of the speech signal, digital signal processing class-based, Normalized data model, modal vibration, High simulation efficiency.)

说明：  详细讲解EM（期望最大化）算法，并使用混合高斯分布示例编程实现解答(Explain EM (expectation maximization) algorithm in detail, and use mixed Gaussian distribution example programming to realize the solution)

说明：  同时正交分解，也是对MP的改进，实现信号的稀疏分解(At the same time orthogonal decomposition, also MP for improvement, and the signal is sparse decomposition)

用Viterbi algorithm筛选经过含白噪声的信息。equalizer为采用Viterbi algorithm，有效减少ISI(码间串扰)，detector为简单的检验器。对比两者的误码率。信息数量为10001bit(using Viterbi algorithm method selecting the data. compared with simple detector. data length are 10001bits. Viterbi algorithm can reduce the affect of ISI （intersymbol interference）)

利用Matlab生成二维随机裂隙，控制裂隙密度、倾向、迹长分布函数、均值、标准差(Using MATLAB to generate two-dimensional stochastic fractures and control the density, tendency, trace length distribution function, mean and standard deviation of fractures)

非线性几何的matlab程序，使用matlab进行了仿真。程序代码简洁，有详细注释(Nonlinear geometry of the matlab program, the use of MATLAB simulation. The code is simple, there are detailed notes )
