这里是几篇关于语音增强中有声无声估计的VAD算法的文献，希望和大家一起讨论，做出与之相关的matlab源代码。(Here are a few on the speech enhancement in a silent voice has estimated VAD algorithm literature, hope and everyone together to discuss and make related matlab source code.)

说明：  已知一组数据,如何用matlab画出它的概率密度分布图,给出具体程序 并且得出分布图后,如何对图进行积分,进而得到分布函数(Given a set of data, how to draw it with matlab probability density distribution maps, specific procedures are given and draw maps, how points on the graph, and then by distribution function)

采用MATLAB中的函数filter2对受噪声干扰的图像进行均值滤波(Using MATLAB functions in filter2 image noise interference by mean filter)

　　　近20年来，阵列信号处理已成为信号处理的一个重要分支，本次实验就是通过MUSIC（Multiple Signal Classification）算法对混叠有高斯白噪声的双信源信号进行频谱分析。(Space there is more than one letter (No.) source, it is often necessary to separate these signals in order to track or detect the spatial signal we are interested in, inhibition of those who are considered interference signal. To this end, the need to use the antenna array to receive multiple spatial signal analysis and processing of the the spatial signal received by the antenna array known as array signal processing. The past 20 years, array signal processing has become an important branch of signal processing, this experiment is the MUSIC (Multiple Signal Classification) algorithm aliasing Gaussian white noise dual source signal spectrum analysis.)

对于时隙aloha在matlab上的研究及分析，属参考资料(Slot aloha research and analysis, is a reference in matlab)

matlab solution for FEM equipotential lines

beamforming, capon, 和music 三种波达方向定位算法的matlab仿真源代码。(出二维图，频率和DOA的对应关系)(beamforming, capon, and music of three DOA positioning algorithm matlab simulation source code. (A two-dimensional diagram, the corresponding frequency and DOA Relations))

一个变步长仿射投影算法，包括论文及仿真代码，已调试通过(A variable step-size affine projection algorithm, including the papers and the simulation code, has been debugged)

matlab 5手册，方便查看，使用学习手册(Matlab 5 manual, convenient to view，Use manual)

串的一些基本运算，删除一段子串，置换，求s串中从start位置开始长度为len的子串等等(Some of the basic string operations, delete a substring, replacement, seeking s string starting from the start position of the sub-string of length len, etc.)
