Three-band compactly supported orthogonal interpolatingscaling function
Jian‐Kang Zhang, Bao · Electronics Letters · 1998
The authors construct a three-band compactly supported orthogonal scaling function with an integer-shifted sampling property. Walter's sampling theorem for wavelet subspaces corresponding to this scaling function has a compactly supported interplant. Therefore, the signals in multiresolution spaces can be reconstructed quickly and accurately without any truncation errors.
