kalman 滤波器使用介绍，初学者的参考,最好先学习一下其推到过程(kalman filter using the introduction of reference for beginners, it is best to first learn about the process of pushing)

回归分析中，检验自变量的重要性，将变量一个一个引入引入变量的条件是其偏回归平方和经检验时显著的，在引入新变量的同时，对已入选的变量逐个检验，将不显著的变量剔除。(The importance of the independent variables of regression analysis, test, introducing variable is introduced one by one into the condition of variable is the partial regression sum of squares in significantly after inspection, and at the same time of introducing new variables, for the selected variables one by one test, will not be significant variables.)

通过MATLAB对4G OFDM基带系统进行仿真模拟，对系统性能进行分析，以待后进学习研究。(By MATLAB on 4G OFDM baseband system simulation, system performance analysis to be less advanced study and research.)

Almouti STBC Bit error comparison with MRC

（1） 本系统用到四种神经网络对漏电嫌疑系数进行预测，分别是BP神经网络、RBF神经网络、GRNN神经网络、Elman神经网络，通过对神经网络结构参数的设置和调试，可以得到很好的预测效果，实际值和预测值之间的误差能达到5 以内。 （2） 本系统使用matlab做GUI界面，在界面上就可以分别对这四种神经网络的结构参数进行设置，从而可以调整神经网络的结构，达到较好的预测精度。 ((1) The system used four neural network to predict the suspected leakage coefficient, respectively, the BP neural network, RBF neural network, GRNN neural network, Elman neural network, the neural network structure parameter setting and commissioning, can get very good prediction, between the actual and predicted values ​ ​ of error of less than 5 . (2) the use matlab to do the GUI interface, the interface can each of these four neural network structure parameters set, the structure of the neural network, which can be adjusted to achieve better prediction accuracy.)

物理光学主要内容的仿真模拟，如双缝干涉，牛顿环现象，夫琅禾费衍射，菲涅尔衍射等(The main content of the physical optics simulation, such as the double-slit interference phenomenon of Newton' s rings, Fraunhofer diffraction Fresnel diffraction)

matlab初学者必备书籍资料，非常有用。我就是从这里入门的。快来分享吧~(help matlab study)
