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。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)

其基本思想是:采用信号与噪声的状态空间模型,利用前一时刻地估计值和现时刻的观测值来更新对状态变量的估计,求出现时刻的估计值。它适合于实时处理和计算机运算。
(The basic idea is: use of signal and noise state-space model, the estimated value of the previous time and are always observations to update the estimated state variables, find an estimate of time there. It is suitable for real-time processing and computing.)
