Information-Theoretic Fairness with A Bounded Statistical Parity Constraint
Amirreza Zamani, Abolfazl Changizi, Ragnar Thobaben +1
In this paper, we study an information-theoretic problem of designing a fair representation that attains bounded statistical (demographic) parity. More specifically, an agent uses…
On Random Subset Generalization Error Bounds and the Stochastic Gradient Langevin Dynamics Algorithm
Borja Rodríguez-Gálvez, Germán Bassi, Ragnar Thobaben +1
In this work, we unify several expected generalization error bounds based on random subsets using the framework developed by Hellström and Durisi [1]. First, we recover the bounds…
Multi-tone Signal Optimization for Wireless Power Transfer in the Presence of Wireless Communication Links
Boules A. Mouris, Hadi Ghauch, Ragnar Thobaben +1
In this paper, we study optimization of multi-tone signals for wireless power transfer (WPT) systems. We investigate different non-linear energy harvesting models. Two of them are…
Multi-Phase Smart Relaying and Cooperative Jamming in Secure Cognitive Radio Networks
Pin-Hsun Lin, Frédéric Gabry, Ragnar Thobaben +2
In this paper we investigate cooperative secure communications in a four-node cognitive radio network where the secondary receiver is treated as a potential eavesdropper with respe…
Communication and Interference Coordination
Ricardo Blasco-Serrano, Ragnar Thobaben, Mikael Skoglund
We study the problem of controlling the interference created to an external observer by a communication processes. We model the interference in terms of its type (empirical distrib…
Bilayer LDPC Convolutional Codes for Half-Duplex Relay Channels
Zhongwei Si, Ragnar Thobaben, Mikael Skoglund
In this paper we present regular bilayer LDPC convolutional codes for half-duplex relay channels. For the binary erasure relay channel, we prove that the proposed code construction…
