比较四分量信号的不同时频分布结果,小波分析。(Compare the results of time-frequency distribution of the four components of the signal)

MUSIC算法[1] 是一种基于矩阵特征空间分解的方法。从几何角度讲，信号处理的观测空间可以分解为信号子空间和噪声子空间，显然这两个空间是正交的。信号子空间由阵列接收到的数据协方差矩阵中与信号对应的特征向量组成，噪声子空间则由协方差矩阵中所有最小特征值（噪声方差）对应的特征向量组成。MUSIC算法就是利用这两个互补空间之间的正交特性来估计空间信号的方位。噪声子空间的所有向量被用来构造谱，所有空间方位谱中的峰值位置对应信号的来波方位。MUSIC算法大大提高了测向分辨率，同时适应于任意形状的天线阵列，但是原型MUSIC算法要求来波信号是不相干的。(clear all clc List0= E:DOA估计仿真 List00=[ 2013-10-31_12_44_31 ] for Li=1:1 List1=strcat(List0,List00(Li,:), Data ) In_p=[List1, ChanData ] 输入数据目录 Out_p=strcat([List1, DataDOA ]) 输出数据目录 NLen=10000 分段长度 M=16 r=15 c=299792458 List=List1(end-19:end-1) 选择目录 if(~exist(Out_p, )) mkdir(Out_p) end )

BP神经网络的通用代码，简单易懂，写法精练(BP neural network, the common code, easy to understand, concise writing)

该程序使用matlab开发的规划中的经典算法——基于对偶仿射理论的内点法，在工程中是很常用的(The program developed by the use of matlab classical planning algorithm- based on the theory of dual affine interior point method, in the projects is a very commonly used)

图像受到裁剪攻击时的一些算法 只要输入图像和想要裁剪的位置 就可以得到想要的结果(Images by cutting attack some algorithm as long as the input image and want to cut position can be the desired results)

窗函数法滤波器设计程序 对学习数字信号处理很有用(Filter window function method to study the design process of digital signal processing useful)

The second line simply displays the matched image, the third line gets the histogram of the matched image, and the last line plots the histogram, which should match the specified PDF. Remember the PDF is supplied to the histogram equalization function, not a CDF, it automatically creates a CDF from the PDF supplied to it.
