Off-the-grid Recovery of Time and Frequency Shifts with Multiple Measurement Vectors
Maral Safari, Sajad Daei, Farzan Haddadi
We address the problem of estimating time and frequency shifts of a known waveform in the presence of multiple measurement vectors (MMVs). This problem naturally arises in radar im…
Living near the edge: A lower-bound on the phase transition of total variation minimization
Sajad Daei, Farzan Haddadi, Arash Amini
This work is about the total variation (TV) minimization which is used for recovering gradient-sparse signals from compressed measurements. Recent studies indicate that TV minimiza…
A Greedy Algorithm for Matrix Recovery with Subspace Prior Information
Hamideh. S Fazael Ardakani, Sajad Daei, Farzan Haddadi
Matrix recovery is the problem of recovering a low-rank matrix from a few linear measurements. Recently, this problem has gained a lot of attention as it is employed in many applic…
One Bit Spectrum Sensing in Cognitive Radio Sensor Networks
Hadi Zayyani, Farzan Haddadi, Mehdi Korki
This paper proposes a spectrum sensing algorithm from one bit measurements in a cognitive radio sensor network. A likelihood ratio test (LRT) for the one bit spectrum sensing probl…
