Gridless Parameter Estimation in Partly Calibrated Rectangular Arrays
Tianyi Liu, Sai Pavan Deram, Khaled Ardah +3
Spatial frequency estimation from a mixture of noisy sinusoids finds applications in various fields. While subspace-based methods offer cost-effective super-resolution parameter es…
A tensor model for the calibration of air-coupled ultrasonic sensor arrays in 3D imaging
Raphael Müller, Gianni Allevato, Matthias Rutsch +4
Arrays of ultrasonic sensors are capable of 3D imaging in air and an affordable supplement to other sensing modalities, such as radar, lidar, and camera, i.e. in heterogeneous sens…
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…
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…
