Decomposition patterns of different M-band multiwavelet packet transforms (taking M = 2 and k = 3 as an example). The pattern in (a) corresponds to the standard M-band multiwavelet decomposition scheme and that in (d) corresponds to a kind of multiwavelet decomposition scheme that presents the finest frequency-domain partition. The patterns in (b-c) correspond to two other possible decomposition schemes respectively
