Blind super-resolution of point sources via fast iterative hard thresholding
Zengying Zhu, Jinchi Chen, Weiguo Gao
In this work, we develop a provable fast algorithm for blind super-resolution based on the low rank structure of vectorized Hankel matrix associated with the target matrix. Theoret…
Stability and Super-resolution of MUSIC and ESPRIT for Multi-snapshot Spectral Estimation
Weilin Li, Zengying Zhu, Weiguo Gao +1
This paper studies the spectral estimation problem of estimating the locations of a fixed number of point sources given multiple snapshots of Fourier measurements collected by a un…
Vectorized Hankel Lift: A Convex Approach for Blind Super-Resolution of Point Sources
Jinchi Chen, Weiguo Gao, Sihan Mao +1
We consider the problem of resolving point sources from samples at the low end of the spectrum when point spread functions (PSFs) are not known. Assuming that the spectrum…
Exact matrix completion based on low rank Hankel structure in the Fourier domain
Jinchi Chen, Weiguo Gao, Ke Wei
Matrix completion is about recovering a matrix from its partial revealed entries, and it can often be achieved by exploiting the inherent simplicity or low dimensional structure of…
