Density Criteria for the Identification of Linear Time-Varying Systems
Céline Aubel, Helmut Bölcskei
This paper addresses the problem of identifying a linear time-varying (LTV) system characterized by a (possibly infinite) discrete set of delays and Doppler shifts. We prove that s…

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".…
