功率谱估计及其MATLAB仿真.经典功率谱估计是将数据工作区外的未知数据假设为零,相当于数据加窗。经典功率谱估计方法分为:相关函数法(BT法)、周期图法以及两种改进的周期图估计法即平均周期图法和平滑平均周期图法,其中周期图法应用较多,具有代表性。(The power spectrum estimation and simulation of MATLAB. Classic power spectrum estimation is unknown data in the data outside the workspace is assumed to be zero, equivalent to the data window. Classic power spectrum estimation method is divided into: the correlation function method (BT Act), the periodogram and two improved cycle diagram estimation method the average periodogram and smoothed average periodogram, which the periodogram method used more often, on behalf of sex.)
