Generalized Line Spectral Estimation via Convex Optimization
Generalized Line Spectral Estimation via Convex Optimization
Line spectral estimation is the problem of recovering the frequencies and amplitudes of a mixture of a few sinusoids from equispaced samples. However, in a variety of signal processing problems arising in imaging, radar, and localization, we do not have access directly to such equispaced samples. Rather, we only observe …
