From: Impulsive noise rejection method for compressed measurement signal in compressed sensing
The first reconstruction example when y was corrupted by impulsive noise. (a) The 128- D y corrupted by six impulsive noise, (b) the original 256-D s (k = 25), and (c) the signal reconstructed from (a) by OMP-PKS. In (b, c), the area to the left of the red dashed line belongs to the third-level subband; the area to the right belongs to the first- and the second-level subbands.
