Amplitude and frequency estimates of the sinusoids obtained with OMP, CoSaMP, ESPRIT, root MUSIC and AMP-CTLS from 15 independent Monte-Carlo trials. The estimates are compared with the true parameters. Subscripts of OMP and CoSaMP denote numbers of grid points. Note that in OMP100M, all of the sinusoids exactly lie on the grid points. The results of conventional MP methods and spectral analysis methods are, respectively, shown in (a) and (b) for better readability.
