摘要
利用高斯小波和由它生成的Hermite函数为窗口函数,进行窗口Fourier变换,由此构造了一类同构映射,并且所得的像空间是一类再生核空间.最后借助该再生核空间建立了局部算子.
In this paper, the Hermite function can be got by Gauss wavelet, we use them as the windowed function in windowed Fourier are a type of reproducing transform, then a family of isomorphic mapping are constructed, such that image spaces kernel spaces. Finally we establish localization operators based on the reproducing kernel spaces.
