Comparison of probabilities of exact reconstruction for different numbers of measurements with different dimensions of measurement matrices (N = 256, k = 40). Frame a was obtained from l 0-norm minimization with ρ = 0.8. Frame b was obtained from l q-norm minimization with q = 0.8 and ρ = 0.8. In frame a and b, t = 1, 2, 4 mean the dimensions of the measurement matrices are M × N, (M/2) × (N/2), and (M/4) × (N/4), respectively
