High accuracy multiwavelets with short supports
Artur Sowa · IEEE Transactions on Signal Processing · 1998
We show how to construct multiwavelets from wavelets. The multiwavelets resulting from such constructions retain accuracy and regularity or the original wavelets and are all supported on a shorter interval than the original wavelets. In fact, we can arrange, at the expense of the number of channels, to obtain any accuracy obtainable for compactly supported wavelets and support in a prescribed neighborhood of the unit interval.
