Beurling-type density criteria for system identification
V. Vlačić, C. Aubel, H. Bölcskei
This paper addresses the problem of identifying a linear time-varying (LTV) system characterized by a (possibly infinite) discrete set of delay-Doppler shifts without a lattice (or…

Deterministic Performance Analysis of Subspace Methods for Cisoid Parameter Estimation
Céline Aubel, Helmut Bölcskei
Performance analyses of subspace algorithms for cisoid parameter estimation available in the literature are predominantly of statistical nature with a focus on asymptoticeither…

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…
