Figure 6From: Robust reconstruction algorithm for compressed sensing in Gaussian noise environment using orthogonal matching pursuit with partially known support and random subsamplingThe average PSNR of reconstructed results by DCS-SOMP and OMP-PKS+RS at M / N = 0.4 from y corrupted by Gaussian noise at (a) σ2 = 0.05, (b) σ2 = 0.1, (c) σ2 = 0.15, and (d) σ2 = 0.2.Back to article page
