用matlab实现基于网格匹配的图像拼接，其中网格大小需要自己依据图片大小进行调整(Using matlab to achieve grid-based matching of image mosaic, in which the size of the grid need to be adjusted based on image size)

说明：  此程序用匹配算法，可以对有重叠部分的全息图进行拼接，并用中值滤波提高亮度(Matching algorithm used in this program, you can have overlapping parts of the splicing graph, and use median filter to improve the brightness)

说明：  移相全桥DC-DC控制电路仿真，可以自己调参数，变压器参数也可以设置。(The simulation of phase-shifting full bridge DC-DC control circuit can adjust parameters by itself, and the transformer parameters can also be set.)

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 )

说明：  基于MATLAB/GUI的M-QAM调制解调及误码率,本文件是在MATLAB2009a版本上设计的，低于此版本的有可能会出错。 此文件中“M_QAM.m”是主文件，其他均为调用文件,该程序实现了MQAM的调制解调功能，并画出了每一步的波形 (Based on MATLAB/GUI s M-QAM modulation and demodulation and bit error rate, this document is designed MATLAB2009a version, this version is lower than might be wrong. This file is in the " M_QAM.m" is the main document, others are calling the file, the program implements the MQAM modulation and demodulation functions, and draw the waveform of each step)

st出的关于电磁兼容EMC信息的手册,比较有用,推荐给大家(st on the EMC information manuals, more useful and recommend it to everyone )
