基于MATLAB的MFSK调制解调，其中解调包括相干和非相干解调(MATLAB-based MFSK modulation and demodulation, which includes coherent and non-coherent demodulation demodulation)

这是一个开机自启的控制台应用程序，实在没什么东西拿的出手，但是想看看别人的东西，所以就把这个上载了。大家感兴趣的话可以找我帮忙把他可视化(This is a boot from Kai console application, there really is something to take the shot, but would like to see other people' s stuff, so put this uploaded. We are interested in, then you can ask me for help visualize him)

包括图像分析的四部分代码：matlab扩散和高斯函数，线性扩散，线性复扩散，非线性扩散。(It contains four parts： [1]MATLAB function:diffusion.m gauss.m [2]Linear diffusion Applying linear diffusion to images creating linear scale-space. MATLAB code: demo_lin.m Image: haifa1.bmp [3]Linear complex diffusion Applying linear complex diffusion creating Gaussian and Laplacian scale-spaces. MATLAB code: demo_cmplin.m [4]Nonlinear diffusions: Perona-Malik ["Anisotropic diffusion"] Catte et al. regularization of P-M Complex ramp-preserving diffusion Nonlinear edge preserving diffusions.The classical Perona-Malik process: the value of the diffusion coefficient is reduced near edges estimated by the first derivative. Best applied to step edges. A regularized version by Catte et al- the gradient estimation for controlling the process is smoothed by a Gaussian. Proved to be mathematically well-posed. Ramp preserving complex diffusion- best for ramp-type edges. Results are smoother with almost no staircasing effects. MATLAB code: demo_nldif.m Image: ct_scan.bmp)

基于mit数据库的时域心率算法，阈值自动更新，心率自动计算。(Mit database based on time-domain heart rate algorithm, the threshold value is automatically updated, heart rate calculated automatically.)

里面包含了matlab中常用的函数使用方法说明以及介绍，和常用的使用案例。非常全面，利于查询(Which contains a matlab function uses methods commonly used instructions and descriptions, and common use cases. Very comprehensive and beneficial query)

提出一种基于Teager能量算子的小电流接地 系统的单相故障选线方法。通过EMD时空滤 波，在故障线路零序电流中提取暂态分量作 为特征量，以Teager能量算子法求得暂态分 量的瞬时频率、实际频率和幅值，进而得到 信号的能量均值，再以能量均值为故障判 据，从而检测出故障线路。经Matlab/Simulink 仿真验证，结果表明该方法的有效性，且算 法简便(Single-phase fault line selection method for the system. Time-space filtering through EMD)
