these matlab files are different modulation techniques in communication

surf 特征提取 点特征 尺度不变性 黑森林矩阵(surf feature extraction)

遗传算法，主要用于解决雷达成像中的insar干涉定标时的敏感度问题。(Genetic Algorithm, mainly used to solve the problem of the sensitivity of the radar imaging insar interferometric calibration time.)

立体匹配 获得立体图像左右视图的视差图代码(Stereo matching to obtain three-dimensional view of the disparity map image around the code)

The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been implemented for a 2x2 system. The reader can program other variations. The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.
