Robustness of Two-Dimensional Line Spectral Estimation Against Spiky Noise
Iman Valiulahi, Farzan Haddadi, Arash Amini
The aim of two-dimensional line spectral estimation is to super-resolve the spectral point sources of the signal from time samples. In many associated applications such as radar an…
