Title: The Uniformity of Non-Uniform Gabor Bases


Although non-uniform (irregular) Gabor bases have attracted a lot of attention there hasn't been a single documented example of a compactly supported orthonormal Gabor basis that is actually non-uniform (irregular). We show that if the support of the generating function is an interval then the Gabor system must be regular. We also show that truly irregular Gabor bases exist in higher dimensions.
