Almost lossless analog signal separation and probabilistic uncertainty relations
David Stotz, Erwin Riegler, Eirikur Agustsson +1
We propose an information-theoretic framework for analog signal separation. Specifically, we consider the problem of recovering two analog signals, modeled as general random vector…
A Theory of Super-Resolution from Short-Time Fourier Transform Measurements
Céline Aubel, David Stotz, Helmut Bölcskei
While spike trains are obviously not band-limited, the theory of super-resolution tells us that perfect recovery of unknown spike locations and weights from low-pass Fourier transf…
Characterizing degrees of freedom through additive combinatorics
David Stotz, Helmut Bölcskei
We establish a formal connection between the problem of characterizing degrees of freedom (DoF) in constant single-antenna interference channels (ICs), with general channel matrix,…
Information-Theoretic Limits of Matrix Completion
Erwin Riegler, David Stotz, Helmut Bölcskei
We propose an information-theoretic framework for matrix completion. The theory goes beyond the low-rank structure and applies to general matrices of "low description complexity".…
