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…
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…
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…
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…
