A multiresolution analysis is a nested chain of related approximation
spaces.This nesting in turn implies relationships among interpolation bases in
the approximation spaces and their derived wavelet spaces. Using these
relationships, a necessary and sufficient condition is given for existence of
interpolation wavelets, via analysis of the corresponding scaling functions. It
is also shown that any interpolation function for an approximation space plays
the role of a special type of scaling function (an interpolation scaling
function) when the corresponding family of approximation spaces forms a
multiresolution analysis. Based on these interpolation scaling functions, a new
algorithm is proposed for constructing corresponding interpolation wavelets
(when they exist in a multiresolution analysis). In simulations, our theorems
are tested for several typical wavelet spaces, demonstrating our theorems for
existence of interpolation wavelets and for constructing them in a general
multiresolution analysis
