Semantic-Preserving Image Coding based on Conditional Diffusion Models
Francesco Pezone, Osman Musa, Giuseppe Caire +1
Semantic communication, rather than on a bit-by-bit recovery of the transmitted messages, focuses on the meaning and the goal of the communication itself. In this paper, we propose…
Resilient Design of 5G Mobile-Edge Computing Over Intermittent mmWave Links
Nicola di Pietro, Mattia Merluzzi, Emilio Calvanese Strinati +1
Two enablers of the 5th Generation (5G) of mobile communication systems are the high data rates achievable with millimeter-wave radio signals and the cloudification of the network'…
On the Degrees of Freedom of Signals on Graphs
Mikhail Tsitsvero, Sergio Barbarossa
Continuous-time signals are well known for not being perfectly localized in both time and frequency domains. Conversely, a signal defined over the vertices of a graph can be perfec…
Uncertainty Principle and Sampling of Signals Defined on Graphs
Mikhail Tsitsvero, Sergio Barbarossa, Paolo Di Lorenzo
In many applications, from sensor to social networks, gene regulatory networks or big data, observations can be represented as a signal defined over the vertices of a graph. Buildi…
Eigenfunctions of Underspread Linear Communication Systems
Sergio Barbarossa, Mikhail Tsitsvero
In this paper we show that the eigenfunctions can be found exactly for systems whose delay-Doppler spread function is concentrated along a straight line and they can be found in ap…
Cognitive MIMO Radio: A Competitive Optimality Design Based on Subspace Projections
Gesualdo Scutari, Daniel P. Palomar, Sergio Barbarossa
Cognitive MIMO Radio: A Competitive Optimality Design Based on Subspace Projections
Competitive Design of Multiuser MIMO Systems based on Game Theory: A Unified View
Gesualdo Scutari, Daniel P. Palomar, Sergio Barbarossa
This paper considers the noncooperative maximization of mutual information in the Gaussian interference channel in a fully distributed fashion via game theory. This problem has bee…
Asynchronous Iterative Waterfilling for Gaussian Frequency-Selective Interference Channels
Gesualdo Scutari, Daniel P. Palomar, Sergio Barbarossa
This paper considers the maximization of information rates for the Gaussian frequency-selective interference channel, subject to power and spectral mask constraints on each link. T…
Optimal Linear Precoding Strategies for Wideband Non-Cooperative Systems based on Game Theory-Part II: Algorithms
Gesualdo Scutari, Daniel P. Palomar, Sergio Barbarossa
In this two-part paper, we address the problem of finding the optimal precoding/multiplexing scheme for a set of non-cooperative links sharing the same physical resources, e.g., ti…
Optimal Linear Precoding Strategies for Wideband Non-Cooperative Systems based on Game Theory-Part I: Nash Equilibria
Gesualdo Scutari, D. P. Palomar, S. Barbarossa
In this two-parts paper we propose a decentralized strategy, based on a game-theoretic formulation, to find out the optimal precoding/multiplexing matrices for a multipoint-to-mult…
Distributed Decision Through Self-Synchronizing Sensor Networks in the Presence of Propagation Delays and Nonreciprocal Channels
Gesualdo Scutari, Sergio Barbarossa, Loreto Pescosolido
In this paper we propose and analyze a distributed algorithm for achieving globally optimal decisions, either estimation or detection, through a self-synchronization mechanism amon…
