Abstract
In this chapter, we identify ideal window functions χI on finite intervals I and time–frequency shift lattices aℤ × bℤ such that the corresponding Gabor systems (Formula presented) are frames for L2(ℝ). Also we consider a stable recovery of rectangular signals f in a shift-invariant space (Formula presented) from their equally-spaced samples f(t0 + µ), µ ϵ aℤ, for arbitrary initial sampling position t0.
