松斋 经典功率谱估计
- 接法又称周期图法,它是把随机序列x(n)的N个观测数据视为一能量有限的序列,直接计算x(n)的离散傅立叶变换,得X(k),然后再取其幅值的平方,并除以N,作为序列x(n)真实功率谱的估计。 -Connection also known as cycle map, it is random sequence x (n) N observational data as a sequence of limited energy, direct calculation x (n) the discr

- Bartlett法:Bartlett平均周期图的方法是将N点的有限长序列x(n)分段求周期图再平均。

- Welch法:Welch法对Bartlett法进行了两方面的修正:一是选择适当的窗函数w(n),并在周期图计算前直接加进去,加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠,这样会使方差减小。
