模态分解的MATLAB工具箱，非常有用的emd分解的工具(Mode decomposition MATLAB toolbox very useful tool emd decomposition)

说明：  这是一个交叉验证函数, 用来选取训练集, 和测试集. 请放在matlab的工具箱中使用(this is a crossvalind. please use it in the matlab tools.)

说明：  极限学习机一种单隐层神经网络，用于数据分类，故障诊断等(ELM is A single hidden layer neural network for data classification, fault diagnosis, etc)

如何减少ISI？分别用NLMS,BLMS，基于符号的LMS算法完成仿真，并比较结果，包括不同信道参数w，不同数据块长度L对其的影响。(How to reduce the ISI? Respectively NLMS, BLMS, symbol-based LMS algorithm to complete the simulation, and compare the results, including different channel parameters w, different data block length L of its impact.)

三相pwm逆变并网仿真模型，相关研究的人可作参考(Three-phase pwm inverter grid simulation model can be used for studies of human reference)

说明：  对新冠肺炎病例传播数据进行清洗，并进行可视化，包含流向地图和桑基图。(The novel coronavirus pneumonia transmission data were cleaned and visualized, including flow maps and sonkey maps.)

本程序是运用MATLAB程序设计实现卡尔曼滤波器，给出了具体的设计格式和参数。(This procedure is to use MATLAB programming Kalman filter, given specific design format and parameters.)

Nothing to do, we need to learn how to trick something on the webs

自己编写的一个单载波时域均衡的程序，采用的是线性MMSE均衡算法(When I have written a single carrier domain equalization program, using the linear MMSE equalization algorithm)
