摘要: 該文根據多子波采樣定理，構造了正交插值多子波，從而可直接用信號的采樣值作為初始值，使離散多子波變換的預濾波算子簡化為單位算子。Abstract: This paper presents the construction of compactly supported, interpolating or-thogonal multiwavelet based on wavelet sampling theorem. With the new interpolation orthogonal multiwavelet base, wavelet coefficients in the multiresolution representation can be directly obtained from a sampled signal. Thus the initialization of the discrete wavelet transform (prefiltering) can be simplified to the identity operator.
