HHT
把HHT和神经网络结合起来，识别出是否故障。对于HHT变换，这里用到的是它的IMF分解，然后用能量理论来判别哪些模组是虚假分量，哪些是是真实分量。对于EMD分解后的谱进行特征提取 ，利用的理论基础就是模糊熵。计算出真实 分量的模糊熵，作为输入层；输出层为两个神经元，为0（故障 ）1（正常 （正常 ）判别该信号是否出现故障。(The combination of HHT and neural network to identify whether the fault. For the HHT transform, here is the use of its IMF decomposition, and then use the energy theory to determine which module is false, which is true component. The theoretical basis for the feature extraction of the spectrum after EMD decomposition is fuzzy entropy. The fuzzy entropy of the real component is calculated, as the input layer, the output layer is two neurons, which is 0 (fault) 1 (normal) to determine whether the signal is faulty.)

m_sequence
一个简单的m序列产生函数，通过调用primpoly获得本原多项式，然后通过移位循环寄存器产生所需要的序列。自相关图形上能看到峰值旁瓣电平(PSL)和积累旁瓣电平(ISL)。(A simple code for generate m-series pseudo-random sequence based PRIMPOLY function which we get the prime polynomials first,then we get the feedback connect coefficient of the cycle shift registers which generate m-series sequency. the PSL and ISL of autocorrelate function is computed on the figure. )
