Geometry-Aware Channel Aging in MIMO Systems: When Is Kronecker Separability Enough?
Steven Rivetti, Gabor Fodor, Emil Bjornson +1
This letter investigates when Kronecker-separable spatial correlation approximates the covariance of multiple-input-multiple-output (MIMO) channels. We propose a geometry-aware cha…
Cramer-Rao Bound Analysis of Bistatic ISAC Under Partial Symbol Knowledge and Clutter
Steven Rivetti, Gabor Fodor, Emil Bjornson +1
Integrated sensing and communication (ISAC) systems rely on communication waveforms to perform sensing tasks, thus making their sensing performance strongly dependent on the level…
On the Impact of Channel Aging and Doppler-Affected Clutter on OFDM ISAC Systems
Steven Rivetti, Gabor Fodor, Emil Björnson +1
The temporal evolution of the propagation environment plays a central role in integrated sensing and communication (ISAC) systems. A slow-time evolution manifests as channel aging…
Millimeter-Wave Joint Radar and Communications With an RIS-Integrated Array
Steven Rivetti, Ozlem Tugfe Demir, Emil Bjornson +1
In the context of the joint radar and communications (JRC) framework, reconfigurable intelligent surfaces (RISs) emerged as a promising technology for their ability to shape the pr…
Clutter-Aware Target Detection for ISAC in a Millimeter-Wave Cell-Free Massive MIMO System
Steven Rivetti, Ozlem Tugfe Demir, Emil Bjornson +1
In this paper, we investigate the performance of an integrated sensing and communication (ISAC) system within a cell-free massive multiple-input multiple-output (MIMO) system. Each…
Destructive and constructive RIS beamforming in an ISAC-multi-user MIMO network
Steven Rivetti, Ozlem Tugfe Demir, Emil Bjornson +1
Integrated sensing and communication (ISAC) has already established itself as a promising solution to the spectrum scarcity problem, even more so when paired with a reconfigurable…
Malicious Reconfigurable Intelligent Surfaces: How Impactful can Destructive Beamforming be?
Steven Rivetti, Ozlem Tugfe Demir, Emil Bjornson +1
Reconfigurable intelligent surfaces (RISs) have demonstrated significant potential for enhancing communication system performance if properly configured. However, a RIS might also…
Secure Spatial Signal Design for ISAC in a Cell-Free MIMO Network
Steven Rivetti, Emil Bjornson, Mikael Skoglund
In this paper, we study a cell-free multiple-input multiple-output network equipped with integrated sensing and communication (ISAC) access points (APs). The distributed APs are us…
