Figure 4From: Deterministic construction of Fourier-based compressed sensing matrices using an almost difference set Reconstruction SNR of the three sensing matrices in noisy compressed sensing. The figure sketches the reconstruction SNR of our new class (asterisks), random partial Fourier (white circle), and chirp sensing (white triangle) matrices from noisy measurements with SNR input = 15 dB, where M = 256 and N = 2,056 for our new sensing and random partial Fourier matrices, while M = 257 and N = 2,056 for chirp sensing codes.Back to article page
