Line Spectral Estimation Using a G-Filter: Atomic Norm Minimization with Multiple Output Vectors
Jiale Tang, Bin Zhu
We propose an atomic norm minimization (ANM) estimator of frequencies in a noisy complex sinusoidal signal that integrates Georgiou's filter bank (G-filter) with multiple output ve…

Line Spectral Analysis Using the G-Filter: An Atomic Norm Minimization Approach
Bin Zhu, Jiale Tang
The area of spectral analysis has a traditional dichotomy between continuous spectra (spectral densities) which correspond to purely nondeterministic processes, and line spectra (D…

When atomic norm meets the G-filter: A general framework for line spectral estimation
Bin Zhu, Jiale Tang
This paper proposes a novel approach for line spectral estimation which combines Georgiou's filter bank (G-filter) with atomic norm minimization (ANM). A key ingredient is a Carath…
