超混沌chen-lee系统引入一个非线性状态反馈控制，将混沌Chen-Lee系统构造成四维超混沌系统。将这个四维超混沌系统作为驱动系统。采用主动控制方法构造一个响应系统，进一步选择适当的控制器使驱动-响应系统达到有限时间同步。(Hyperchaotic chen-lee system into a nonlinear state feedback control, the chaos Chen-Lee system constructed four-dimensional hyperchaotic system. This four-dimensional hyperchaotic system as the drive system. Using active control methods to create a response system, to further select the appropriate controller to drive- response system to the finite time synchronization.)

该文件详细介绍了各种最小二乘算法的实现步骤，给出了实验仿真的例子和MATLAB程序，对学校最小二乘相关算法的人非常好(The document details the steps of various least squares algorithm, an experimental simulation examples and MATLAB programs for school-related least squares algorithm are very good)

when SNR is high , 1st sample estimator provides good estimate of A. it has no noise effect . so we don’t need averaging effect to reduce noise when SNR is high. However variance is still low in sample mean estimator which shows that in reality ,sample mean is good estimator than 1st sample estimator. So, for high SNR, we do not need to reduce the effect of noise by averaging. or we can say that for high SNR let say >1000 , 1st sample estimator got reduced noise. But as for as variance is concerned , the sample mean has low variance for high SNR as well.

此程序简单实用，用于数据的特征提取。选取了波形因子、峭度、频段带能量百分比等时域频域特征量。(This procedure is simple and practical, for data feature extraction. Select form factor, kurtosis, band band energy percentage frequency domain characteristics.)
