Abstract
We give a geometric characterization of knot sequences \((s_{n})\), which is a sufficient condition for the corresponding periodic orthonormal spline system of arbitrary order \(k\), \(k\in\mathbb{N}\), is an unconditional basis in the atomic Hardy space on the torus \(H^{1}(\mathbb{T})\).
