Du-Fort-Frankel-Difference

this code shows the implementation of a transmission chain. First, the codage with Gray(MDA-4), then the over sampling, the filtrage before emission, the filtrage in reception with the same filter(in order to be adaptative). then the decision within the value of the final signal in the reception.

In the previous chapters we have encountered a number of ways to process digital images, to recognize objects therein and to

用matlab编写的用于转子动力学分析的有限元程序，可实现转子临界转速和振型分析、稳态响应和瞬态响应分析等功能。()

潮流计算，用matlab解决潮流问题，只要修改其中的部分参数可以实现不同功能(Flow calculation, the trend of using matlab to solve the problem, as long as some of these parameters can be modified to achieve different functions)

将信号用小波函数SYM5分解到第5层，用minimaxi阈值选择对系数进行处理，消除噪声(SYM5 decomposition using the wavelet function signals to the fifth floor, use minimaxi threshold choice to deal with coefficient, eliminate noise)

说明：  关于正交信号中，复数的意义，其实复数是有实际意义的！(On the quadrature signal, the plural meaning, in fact, there is a complex meaningful!)

matlab信号处理详解，希望可以对大家有用！！！！！！(matlab signal processing Xiang Jie, I hope we can be useful! ! ! ! ! !)
