Two-Dimensional Super-Resolution via Convex Relaxation
Iman Valiulahi, Sajad Daei, Farzan Haddadi +1
In this paper, we address the problem of recovering point sources from two dimensional low-pass measurements, which is known as super-resolution problem. This is the fundamental co…

Off-the-grid Two-Dimensional Line Spectral Estimation With Prior Information
Iman Valiulahi, Hamid Fathi, Sajad Daei +1
In this paper, we provide a method to recover off-the-grid frequencies of a signal in two-dimensional (2-D) line spectral estimation. Most of the literature in this field focuses o…

How to exploit prior information in low-complexity models
Sajad Daei, Farzan Haddadi
Compressed Sensing refers to extracting a low-dimensional structured signal of interest from its incomplete random linear observations. A line of recent work has studied that, with…
