用matlab编写的拉普拉斯高斯算子代码（LoG算子），用该函数实现LoG算子提取图像边缘点的功能。(Written by matlab Laplacian of Gaussian operator code (LoG operator), using the LoG operator functions for extracting the image edge points of the function.)

说明：  这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is a space-time block coding based on the MIMO_OFDM Communication System Simulation and Design. This system consists of QPSK modulation and demodulation, IFFT modulation, space time coding and decoding, based on training symbols such as communication channel estimation module.)

频谱选取，一般用于后续向量机的诊断的特征。进行了频谱分析后对每个频带的能量进行分离开。(Spectral selection, generally for subsequent diagnostic feature vector machine. Spectrum analysis conducted after the energy of each frequency band to leave.)

自己写的多分辨率SVD函数，普通SVD也包含在内，采用类似小波多分辨率分析进行SVD降噪、降维，奇异点求解(Multi-resolution SVD function, using wavelet-like multi-resolution analysis for SVD noise reduction, dimension reduction, singular point solution)

完整版的频谱检测算法的MATLAB实现，有原理，有程序，有结果。(Full version of the spectrum to achieve detection algorithm of MATLAB, there are principles, procedures and results.)

这个是利用MATLAB实现的KNN算法的实现(This is achieved using MATLAB algorithm to achieve KNN)

K-SVD可以看做K-means的一种泛化形式，K-means算法总每个信号量只能用一个原子来近似表示，而K-SVD中每个信号是用多个原子的线性组合来表示的。 K-SVD通过构建字典来对数据进行稀疏表示，经常用于图像压缩、编码、分类等应用。(K-SVD can be regarded as a generalized form of K-means. The total K-means algorithm can only approximate one signal for each semaphore, and each signal in K-SVD is a linear combination of multiple atoms To express. K-SVD through the construction of the dictionary to sparse data representation, often used for image compression, encoding, classification and other applications.)
