    %% 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');
