Local Geometry of Nonconvex Spike Deconvolution from Low-Pass Measurements
Maxime Ferreira Da Costa, Yuejie Chi
Spike deconvolution is the problem of recovering the point sources from their convolution with a known point spread function, which plays a fundamental role in many sensing and ima…
Joint Localization and Orientation Estimation in Millimeter-Wave MIMO OFDM Systems via Atomic Norm Minimization
Jianxiu Li, Maxime Ferreira Da Costa, Urbashi Mitra
Herein, an atomic norm based method for accurately estimating the location and orientation of a target from millimeter-wave multi-input-multi-output (MIMO) orthogonal frequency-div…
On the Stability of Super-Resolution and a Beurling-Selberg Type Extremal Problem
Maxime Ferreira Da Costa, Urbashi Mitra
Super-resolution estimation is the problem of recovering a stream of spikes (point sources) from the noisy observation of a few numbers of its first trigonometric moments. The perf…
