(l1,l2)-RIP and Projected Back-Projection Reconstruction for Phase-Only Measurements
Thomas Feuillen, Mike E. Davies, Luc Vandendorpe +1
This letter analyzes the performances of a simple reconstruction method, namely the Projected Back-Projection (PBP), for estimating the direction of a sparse signal from its phase-…
Close Encounters of the Binary Kind: Signal Reconstruction Guarantees for Compressive Hadamard Sampling with Haar Wavelet Basis
Amirafshar Moshtaghpour, José M. Bioucas Dias, Laurent Jacques
We investigate the problems of 1-D and 2-D signal recovery from subsampled Hadamard measurements using Haar wavelet sparsity prior. These problems are of interest in, e.g., computa…
Identifiability Conditions for Multi-channel Blind Deconvolution with Short Filters
Antoine Paris, Laurent Jacques
This work considers the multi-channel blind deconvolution problem under the assumption that the channels are short. First, we investigate the ill-posedness issues inherent to blind…
Jointly Low-Rank and Bisparse Recovery: Questions and Partial Answers
Simon Foucart, Rémi Gribonval, Laurent Jacques +1
We investigate the problem of recovering jointly -rank and -bisparse matrices from as few linear measurements as possible, considering arbitrary measurements as well as rank-…
