Abstract
We consider the problem of spectral analysis of signals composed of sums of multiple amplitude modulated, possibly

harmonically related, sinusoids using a sparse approach. By separating the nonlinear frequency variables using a dictionary of

possible frequency components as well as a spline basis for the amplitude modulation, results in a convex criterion which can be

efficiently solved without worrisome local minima. The resulting method makes no model order assumption and automatically

estimates both the signal parameters and their amplitude modulations
