    相关函数法该方法先由序列估计出自相关函数R,然后对其进行傅立叶变换,得到功率谱估计。当延时和数据长度相比很小的时候可以有良好的估计精度。 (Correlation function method that the method is estimated by the sequence from a correlation function R, then its Fourier transform, the power spectrum estimation. When the length of delay and data can be compared to a very early age have a good estimation accuracy.)

    反馈网络是神经网络的基础 这里提供了神经网络中用到的反馈 这里能充分理解文档的内容就能很好的掌握神经网络的基础。我将各个函数写成了不同的文档 就是便于大家理解。(Feedback network is the basis of the neural network here provides feedback neural network is used here to fully understand the content of the document can very good master the basis of neural network. I will each different function in the form of a document is easy to understand.)
