Construction of Orthogonal Wavelets Using Fractal Interpolation Functions
George C. Donovan, Jeffrey S. Geronimo, Douglas P. Hardin, Peter Massopust · SIAM Journal on Mathematical Analysis · 1996
Fractal interpolation functions are used to construct a compactly supported continuous, orthogonal wavelet basis spanning $L^2 (\mathbb{R})$. The wavelets share many of the properties normally associated with spline wavelets, in particular, they have linear phase.
