Abstract
For any positive real numbers A, B, and d satisfying the conditions\(\frac{1}{A} + \frac{1}{B} = 1\), d>2, we construct a Gabor orthonormal basis for L2(ℝ), such that the generating function g∈L2(ℝ) satisfies the condition:∫ℝ|g(x)|2(1+|x|A)/logd(2+|x|)dx < ∞ and\(\int_{\hat {\mathbb{R}}} {\left| {\hat g(\xi )} \right|^2 (1 + \left| \xi \right|^B )/\log ^d (2 + \left| \xi \right|)d\xi< \infty } \).
