本文介绍kalman滤波的基本原理及发展现状，主要从模型的建立和非线性模型的线性化两方面进行介绍(In this paper, the basic principle of kalman filter and the development present situation, mainly from the establishment of model and the linearization of the nonlinear model is presented in two aspects)

这是关于数字预失真的仿真程序，应用LMS急降方法实现系数更新，对失真有很好的效果(This is the digital predistortion simulation program, the drop of the LMS coefficient update method implementation, have a good effect on the distortion)

说明：  Hurst参数用来衡量时间序列的相关程度。给出了AVB, R/S, VT, PG, Wavelet等多种方法。(The degree of dependence of a time serie is measured by Hurst paramrter. AVB, R/S, VT, PG, Wavelet methods are given in this package. )

very cool program finite element method

预报误差法参数辨识-松弛的思想，考虑雨衰 阴影 和多径影响，小波包分析提取振动信号中的特征频率。( Prediction Error Method for Parameter Identification- the idea of relaxation, Consider shadow rain attenuation and multipath effects Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  很好的源码，关于卡尔曼滤波的源码，值得一看(A good source, the source on the Kalman filter, worth a visit)
