Recovery Analysis of Damped Spectrally Sparse Signals and Its Relation to MUSIC
Shuang Li, Hassan Mansour, Michael B. Wakin
One of the classical approaches for estimating the frequencies and damping factors in a spectrally sparse signal is the MUSIC algorithm, which exploits the low-rank structure of an…
