synchronous-identification

说明：  Matlab里计算高维时空混沌OCML的源程序(Matlab to calculate high-dimensional space-time source of chaos OCML)

光纤相干通讯数字相干接收机，算法和子系统。一篇很精简全面的总结。(Digital coherent optical receiver algorithms and subsystems in fiber coherent optical communication. A very good brief summary.)

说明：  本设计为基于MATLAB特征点匹配的指纹识别系统。带有一个GUI界面。主要对指纹图像进行三方面处理：图像预处理、特征提取和特征匹配。图像预处理包括四个步骤：图像分割、滤波增强、二值化、细化，对指纹图像进行预处理后，去除了原图像的冗余部分，方便后续的识别处理；特征提取主要是提取指纹图像细化后的端点和分叉点；特征匹配是利用两个指纹的图像进行特征点比较，来确定两幅图像是否来自于同一手指。(This design is a fingerprint recognition system based on MATLAB feature point matching. With a GUI interface. Fingerprint image is mainly processed in three aspects: image preprocessing, feature extraction and feature matching. Image preprocessing includes four steps: image segmentation, filter enhancement, binarization and thinning. After preprocessing the fingerprint image, the redundant part of the original image is removed to facilitate the subsequent identification processing; feature extraction is mainly to extract the refined endpoint and bifurcation point of fingerprint image; feature matching is to determine the two images by comparing the feature points of two fingerprint images Is it from the same finger.)

说明：  傅里叶函数的表现形式，这个在matlab里面非常的常见，可以作为参考(Fourier form of the function, this is very common in matlab which can be used as reference)

坐标变换，实现3/2和2/2变换。异步电动机矢量控制中使用的(Coordinate transformation, to achieve 3/2 and 2/2 transformation. Vector control induction motor used)

从matlab官网上下载的emd程序，是简化版，适合初学者使用。(The emd program is downloaded from the offical website of matlab,it is a simplified version for beginners.)

简单的if else，和switch分支的小程序，希望大家谅解(Simple if else, and switch branches applet, I hope you understand)

the following file is a matlab program done for thesis based on acoustic echo cancellation using LMS algorithm.
