✦ Synopsis

In this paper we show that there exist wavelet frames that have nice dual wavelet frames, but for which the canonical dual frame does not consist of wavelets, i.e., cannot be generated by the translates and dilates of a single function.  2002 Elsevier Science (USA)

We show that there are duals {x \* n } to a given (nonexact) frame {x n } that are not usual frames. In particular, these duals are not Bessel sequences. We call them pseudo-duals. A characterization and a constructions of pseudo-duals are given. Examples and potential applications of pseudo-dual th

We give a characterization of all (quasi)affine frames in L 2 (R n ) which have a (quasi)affine dual in terms of the two simple equations in the Fourier transform domain. In particular, if the dual frame is the same as the original system, i.e., it is a tight frame, we obtain the well-known characte
