Joint Beamforming and Association Design for MIMO Radar
Urs Niesen, Jayakrishnan Unnikrishnan
A critical task of a radar receiver is data association, which assigns radar target detections to target filter tracks. Motivated by its importance, this paper introduces the probl…
Satellite Positioning with Large Constellations
Urs Niesen, Olivier Leveque
Modern global navigation satellite system receivers can access signals from several satellite constellations (including GPS, GLONASS, Galileo, BeiDou). Once these constellations ar…
Energy-Efficiency Gains of Caching for Interference Channels
Jad Hachem, Urs Niesen, Suhas Diggavi
This paper initiates the study of energy-efficiency gains provided by caching. We focus on the cache-aided Gaussian interference channel in the low-SNR regime. We propose a strateg…
An Information-Theoretic Analysis of Deduplication
Urs Niesen
Deduplication finds and removes long-range data duplicates. It is commonly used in cloud and enterprise server settings and has been successfully applied to primary, backup, and ar…
Degrees of Freedom of Cache-Aided Wireless Interference Networks
Jad Hachem, Urs Niesen, Suhas Diggavi
We study the role of caches in wireless interference networks. We focus on content caching and delivery across a Gaussian interference network, where both transmitters and receiver…
A Layered Caching Architecture for the Interference Channel
Jad Hachem, Urs Niesen, Suhas Diggavi
Recent work has studied the benefits of caching in the interference channel, particularly by placing caches at the transmitters. In this paper, we study the two-user Gaussian inter…
