2*2 mimo-ofdm系统的误码率测量。经过时不变信道(ber of 2*2 mimo-ofdm)

The files included implement the M3 Enigma machine. Rotors.m implements the GUI and enigma.m implements the cipher substitutions. The implementation can be used as an aid to teaching the enigma machine. Also, the source can be used to show how to implement an enigma machine. The files are thoroughly commented and the application can run in MATLAB by just typing rotors

说明：  信息理论与编码——关于信道容量迭代的matlab仿真程序(Information Theory and Coding- on the channel capacity iteration matlab simulation program)

根据本原多项式阶数，产生随机m序列的程序(it produce m sequences knowning the order of the primitive polynomial )

基于Matlab音乐的分类算法以及相应的代码，最后给出了DSP的实现系统框图(Matlab-based music classification algorithm and the corresponding code, and finally given the realization of DSP system block diagram)

说明：  基于主成分分析实现对特征脸的人脸识别，训练，输出识别率等。(Based on principal component analysis to achieve the characteristics of face recognition, training, recognition rate of the output.)

David G.Lowe的SIFT算子在Matlab环境下的实现，尺度不变的特征提取，并对两幅图片的特征点进行匹配，运行前要把siftWin32文件放在Matlab的win目录下，具体请参照README。默认为输入为灰度图像，要处理彩色图片请先转灰度rgb2gray() (The realization of SIFT operator David G.Lowe in the Matlab environment, the scale invariant feature extraction, matching and pictures of the two feature points, the siftWin32 file in the Matlab win directory to run before, please refer to the specific README. The default is the input for the gray image to color image processing, please turn gray by rgb2gray ())

This is the second tutorial of a series of image processing tutorials

matlab求解高阶偏微分方程边界问题，包括bvp4c.m，license.txt和(matlab solving warned partial differential equations of the border issue, bvp4c，sparse2.mexw32)

this package contain a function generate a barker code sequence which is used in phase coded pulse compression performed in the second matlab file
