Abstract

Abstract. This paper deals with a construction of both stationary and nonstationaryM-band tight framelet packets in L2(R) using extension principles.The approach here is different than the method described by Shah and Debnathin [ Explicit construction of M-band tight framelet packets, Analysis,32 (2012) 281-294 ] in that we directly decompose the multiresolution spaceVJ for a fixed level J > 0 to the level 0 with any combined wavelet maskm = [m0,m1, . . . ,mL] satisfying the unitary extension principle conditionM(ξ)M∗(ξ) = IM, where M(ξ) ={mℓ(ξ + 2πpM)}M−1ℓ,p=0.
