正交频分复用其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。(Orthogonal Frequency Division Multiplexing)

MATLAB神经网络30个案例分析，包括全文教程[PDF],还包括源代码（matlab）打包。(MATLAB neural network analysis of 30 cases, including full text tutorial [PDF], also includes the source code (matlab) packaging.)

置换熵，一种度量信号混乱程度的非线性指标，permutation entropy(Permutation entropy, a nonlinear signal indicators measure of disorder, permutation entropy)

EMD或者LMD的能量密度与其平均周期的乘积K值，当K值发生较大变化的时候，证实该分量为白噪声，可以剔除，将剩下的分量进行重构，达到去噪的目的。(The product of K EMD or LMD energy density and average cycle value when the K value was changed greatly, the component for white noise can be eliminated, the remaining components are reconstructed to achieve the purpose of de-noising.)
