Supports of Fourier Transforms of Refinable Frame Functions and Their Applications to FMRA

Yun-zhang LI  Chun-hua HAN  
【摘要】:Let M be a d × d expansive matrix,and FL2(Ω) be a reducing subspace of L2(Rd).This paper characterizes bounded measurable sets in R d which are the supports of Fourier transforms of M-refinable frame functions.As applications,we derive the characterization of bounded measurable sets as the supports of Fourier transforms of FMRA(W-type FMRA) frame scaling functions and MRA(W-type MRA) scaling functions for FL2(Ω),respectively.Some examples are also provided.
