%% Reconstruction from 1-D Complex Dual-Tree Wavelet Transform % Obtain the complex dual-tree wavelet transform of the 1-D noisy Doppler % signal. Reconstruct an approximation based on the level-three detail % coefficients %% % Load the noisy Doppler signal. Obtain the complex dual-tree transform % down to level 3. load noisdopp; wt = dddtree('cplxdt',noisdopp,3,'dtf1'); %% % Plot a reconstruction of the original signal based on the level-three % detail coefficients xr = dddtreecfs('r',wt,'scale',{3},'plot');
