Nuclear Atomic Norm for parametric estimation of sparse channels
Álvaro Callejas-Ramos, Matilde Sánchez-Fernández, Antonia Tulino +1
Parametric channel estimation in mmWave not only enables the anticipated large spectral efficiency gains of \acs{MIMO} systems but also reveals important propagation parameters, al…
Estimation of Interference Correlation in mmWave Cellular Systems
Stefano Tomasin, Raphael Hasler, Antonia M. Tulino +1
We consider a cellular network, where the uplink transmissions to a base station (BS) are interferenced by other devices, a condition that may occur, e.g., in cell-free networks or…
Asymptotic Learning Requirements for Stealth Attacks on Linearized State Estimation
Ke Sun, Iñaki Esnaola, Antonia M. Tulino +1
Information-theoretic stealth attacks are data injection attacks that minimize the amount of information acquired by the operator about the state variables, while simultaneously li…
Gridless Multidimensional Angle of Arrival Estimation for Arbitrary 3D Antenna Arrays
Matilde Sánchez-Fernández, Vahid Jamali, Jaime Llorca +1
A full multi--dimensional characterization of the angle of arrival (AoA) has immediate applications to the efficient operation of modern wireless communication systems. In this wor…
A Single-RF Architecture for Multiuser Massive MIMO via Reflecting Surfaces
Ali Bereyhi, Vahid Jamali, Ralf R. Müller +3
In this work, we propose a new single-RF MIMO architecture which enjoys high scalability and energy-efficiency. The transmitter in this proposal consists of a single RF illuminator…
Rényi Entropy Bounds on the Active Learning Cost-Performance Tradeoff
Vahid Jamali, Antonia Tulino, Jaime Llorca +1
Semi-supervised classification, one of the most prominent fields in machine learning, studies how to combine the statistical knowledge of the often abundant unlabeled data with the…
