关于sliding fourier transform！
请问一下什么是sliding fourier transform算法啊？谢谢～～ 从名称上感觉就是窗口Fourier变换，窗在sliding... 滑动傅立叶变换 The sliding Fourier transform is widely used for extracting time-dependent spectra from time series and has localization properties similar to those of the wavelet transformations. It is described here to provide a contrast to the wavelet transforms. To create a sliding Fourier transform, a time series is cut into a series of smaller series, which are then individually Fourier transformed. This windowing creates a transformation that is localized in time.以上摘自：http://sepwww.stanford.edu/public/docs/sep75/ray2/paper_html/node3.html
