Wavelet packet reconstruction 1-D
Load a signal.
load noisdopp x = noisdopp;
Decompose the signal at level 3 with
sym4 wavelet packets using log energy entropy.
wpt = wpdec(x,3,'sym4','log energy');
Reconstruct the signal from the wavelet packet tree object.
xrec = wprec(wpt);
Compare the original signal with the reconstruction.
