Ambiguities in Direction-of-Arrival Estimation with Linear Arrays
Frederic Matter, Tobias Fischer, Marius Pesavento +1
In this paper, we present a novel approach to compute ambiguities in thinned uniform linear arrays, i.e., sparse non-uniform linear arrays, via a mixed-integer program. Ambiguities…
Extended Successive Convex Approximation for Phase Retrieval with Dictionary Learning
Tianyi Liu, Andreas M. Tillmann, Yang Yang +2
Phase retrieval aims at reconstructing unknown signals from magnitude measurements of linear mixtures. In this paper, we consider the phase retrieval with dictionary learning probl…
Recovery under Side Constraints
Khaled Ardah, Martin Haardt, Tianyi Liu +3
This paper addresses sparse signal reconstruction under various types of structural side constraints with applications in multi-antenna systems. Side constraints may result from pr…
Probability of Resolution of MUSIC and g-MUSIC: An Asymptotic Approach
David Schenck, Xavier Mestre, Marius Pesavento
In this article, the outlier production mechanism of the conventional Multiple Signal Classification (MUSIC) and the g-MUSIC Direction-of-Arrival (DoA) estimation technique is inve…
