Activity Detection in Distributed Massive MIMO With Pilot-Hopping and Activity Correlation
Ema Becirovic, Emil Björnson, Erik G. Larsson
Many real-world scenarios for massive machine-type communication involve sensors monitoring a physical phenomenon. As a consequence, the activity pattern of these sensors will be c…
Over-the-Air Federated Learning with Privacy Protection via Correlated Additive Perturbations
Jialing Liao, Zheng Chen, Erik G. Larsson
In this paper, we consider privacy aspects of wireless federated learning (FL) with Over-the-Air (OtA) transmission of gradient updates from multiple users/agents to an edge server…
Structural Balance Considerations for Networks with Preference Orders as Node Attributes
Olle Abrahamsson, Danyo Danev, Erik G. Larsson
We discuss possible definitions of structural balance conditions in a network with preference orderings as node attributes. The main result is that for the case with three alternat…
Activity Detection in Distributed MIMO: Distributed AMP via Likelihood Ratio Fusion
Jianan Bai, Erik G. Larsson
We develop a new algorithm for activity detection for grant-free multiple access in distributed multiple-input multiple-output (MIMO). The algorithm is a distributed version of the…
Data Size-Aware Downlink Massive MIMO: A Session-Based Approach
Tung T. Vu, Hien Quoc Ngo, Minh N. Dao +2
This letter considers the development of transmission strategies for the downlink of massive multiple-input multiple-output networks, with the objective of minimizing the completio…
Participatory Sensing for Localization of a GNSS Jammer
Glädje Karl Olsson, Erik Axell, Erik G. Larsson +1
GNSS receivers are vulnerable to jamming and spoofing attacks, and numerous such incidents have been reported worldwide in the last decade. It is important to detect attacks fast a…
