Parametric Channel Estimation for RIS-Assisted Wideband Systems

no code implementations18 Dec 2024 Alva Kosasih, Ozlem Tugfe Demir, Emil Bjornson

In this paper, we develop a novel parametric ML channel estimator for RIS-assisted wideband systems, which can handle line-of-sight (LOS) paths in the base station (BS)-RIS and RIS-UE links as well as NLOS paths between the UE, BS, and RIS.

Communicate or Sense? AP Mode Selection in mmWave Cell-Free Massive MIMO-ISAC

no code implementations3 Dec 2024 Weixian Yan, Ozan Alp Topal, Zinat Behdad, Ozlem Tugfe Demir, Cicek Cavdar

Integrated sensing and communication (ISAC) is a promising technology for future mobile networks, enabling sensing applications to be performed by existing communication networks, consequently improving the system efficiency.

Clutter-Aware Target Detection for ISAC in a Millimeter-Wave Cell-Free Massive MIMO System

no code implementations13 Nov 2024 Steven Rivetti, Ozlem Tugfe Demir, Emil Bjornson, Mikael Skoglund

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.

Malicious Reconfigurable Intelligent Surfaces: How Impactful can Destructive Beamforming be?

no code implementations20 Feb 2024 Steven Rivetti, Ozlem Tugfe Demir, Emil Bjornson, Mikael Skoglund

Reconfigurable intelligent surfaces (RISs) have demonstrated significant potential for enhancing communication system performance if properly configured.
