Maximum A Posteriori Direction-of-Arrival Estimation via Mixed-Integer Semidefinite Programming
Tianyi Liu, Frederic Matter, Alexander Sorg +3
We propose a joint sparse maximum a posteriori (MAP) estimator for DOA estimation from multiple snapshots, reformulated as a mixed-integer semidefinite program (MISDP). This enable…
Enabling Research through the SCIP Optimization Suite 8.0
Ksenia Bestuzheva, Mathieu Besançon, Wei-Kun Chen +32
The SCIP Optimization Suite provides a collection of software packages for mathematical optimization centered around the constraint integer programming framework SCIP. The focus of…
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…
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…
Block-sparse Recovery of Semidefinite Systems and Generalized Null Space Conditions
Janin Heuer, Frederic Matter, Marc E. Pfetsch +1
This article considers the recovery of low-rank matrices via a convex nuclear-norm minimization problem and presents two null space properties (NSP) which characterize uniform reco…
Joint Antenna Selection and Phase-Only Beamforming Using Mixed-Integer Nonlinear Programming
Tobias Fischer, Ganapati Hegde, Frederic Matter +3
In this paper, we consider the problem of joint antenna selection and analog beamformer design in downlink single-group multicast networks. Our objective is to reduce the hardware…
