本文研究了周期子集中的Gabor框架集。我们刻画了图中的紧Gabor集,得到了图中的可测子集是图中的Gabor标架集的一些充要条件.我们还刻画了具有紧Gabor集的集合,并在时频移参数的乘积为有理数的情况下,得到了一类紧Gabor集的显式构造.即使如此,我们的结果也是新的。
This paper investigates Gabor frame sets in a periodic subsetof. We characterize tight Gabor sets in, and obtain some necessary/sufficient conditions for a measurable subset ofto be a Gabor frame set in. We also characterize those setsadmitting tight Gabor sets, and obtain an explicit construction of a class of tight Gabor sets in suchfor the case that the product of time-frequency shift parameters is a rational number. Our results are new even if.
