Study of a Sort of Orthogonal Multiple Vector-Valued Trivariate Wavelet Packets
Xiaofeng Wang, Deyao Song · 2009
Wavelet analysis has been developing a widely used mathematical branch for twenty years. In this work, the notion of biorthogonal multiple vector-valued trivariate wavelet packets is introduced. A new feasible method for designing them is presented. Their properties are characterized by using time-frequency analysis method, matrix theory and finite group theory. Three orthogonality formulas are established.
