“…The number of the subbands is chosen in the range [2,12] with 2 as its advancing step. The parameters are SNR = 20 dB, = 20, 푖 ∈ {1, 2, 3, 4, 5, 6}, and 푖 ∈ {0.4, 0.7, 0.2, 0.9, 1.2, 1.5} s. As shown in Figure 10, since the number of the bands is directly related to the sparsity order of the signal, with the increase of , the signal is not sparse enough and the success rate of reconstruction for three algorithms is reduced.…”
