IWT_PBS

Inverse Wavelet Transform (periodized, biorthogonal,symmetric)

Calling Sequence

x = IWT_PBS(wc,L,qmf)

Parameters

Inputs:

wc :

1-d wavelet transform: length(wc)= 2^J.

L :

Coarsest scale (2^(-L) = scale of V_0); L << J;

qmf :

quadrature mirror filter

dqmf:

dual quadrature mirror filter (symmetric, dual of qmf)

Outputs:

x :

1-d signal reconstructed from wc

Description

Suppose wc = FWT_PBS(x,L,qmf,dqmf);

where analysis_qmf is a biorthogonal symmetric quadrature mirror filter as made by [qmf,dqmf] = MakeBSFilter(Request,par);

Then x can be reconstructed by x = IWT_PBS(wc,L,qmf,dqmf);
