Abstract :
A practical method of reconstruction of signals from a small number of random observations is put forward. The method takes advantage of the sparsity of the signal in wavelet domain to reconstruct it in an iterative manner. The proposed method is shown to be quite successful in reconstruction of 1D as well as 2D signals from a few numbers of randomly acquired samples. It also proves to be robust to observation noise.
