emd 经验模态分解过程，及其相关应用，以及具体过程示例(emd Empirical mode decomposition process, and its related applications, as well as specific process examples)

基于镜像延拓法的emd分解，用于解决端点效应(EMD decomposition based on mirror extension method to solve endpoint effect.)

emd分解的一个改进，内含有例子说明，便于各位阅读(An improvement in EMD decomposition.)

tvfemd可进行序列分解，比emd分解效果可能要好一点。(he sifting process is completed using a time varying filter technique.The local cut-off frequency is adaptively designed by fully facilitating the instantaneous amplitude and frequency information. Then nonuniform B-spli
