Greed is Super: A Fast Algorithm for Super-Resolution
Armin Eftekhari, Michael B. Wakin
We present a fast two-phase algorithm for super-resolution with strong theoretical guarantees. Given the low-frequency part of the spectrum of a sequence of impulses, Phase I consi…

Approximating Sampled Sinusoids and Multiband Signals Using Multiband Modulated DPSS Dictionaries
Zhihui Zhu, Michael B. Wakin
Many signal processing problems--such as analysis, compression, denoising, and reconstruction--can be facilitated by expressing the signal as a linear combination of atoms from a w…
