Abstract

An orthonormal wavelet basis on the circle γ is constructed. By estabishing some new theorems on complex spline functions, the \(\mathop L\limits^ \circ _2 (I)\) space can be decomposed into different orthogonal subspaces. Formulas of decomposition and reconstruction imply only two terms.
