Probability of detecting the correct support (i.e., to find the true number of sinusoids with the correct frequencies) for tests T_M (left), HC (middle) and BJ (right) applied to with L = 20. For each given value of β, the N_s amplitudesare equal. Left panel: represents this probability as a function of the sinusoid’s amplitude (N_s = β = 1) and the performances of tests HC and BJ have been added for comparison. The two other panels represent the adaptive tests’ performances as a function of the sinusoids’ amplitude A and the sparsity parameter β. In these twopanels, the probability of correct recovery is indicated in color.
