From Focusing to Con-Focusing: Optimal Power Transfer in Line-of-Sight Near-Field MIMO
Marouan Mizmizi, Sanzhar Yergaliev
Beamfocusing is the established near-field strategy for a large array serving a single-antenna user. We consider the single-user line-of-sight MIMO link, free of multipath, in whic…
Device-Centric ISAC for Exposure Control via Opportunistic Virtual Aperture Sensing
Marouan Mizmizi, Zhibin Yu, Guanglong Du +1
Regulatory limits on Maximum Permissible Exposure (MPE) require handheld devices to reduce transmit power when operated near the user's body. Current proximity sensors provide only…
Echo-Side Integrated Sensing and Communication via Space-Time Reconfigurable Intelligent Surfaces
Marouan Mizmizi, Stefano Tebaldini, Umberto Spagnolini
This paper presents an echo-side modulation framework for integrated sensing and communication (ISAC) systems. A space-time reconfigurable intelligent surface (ST-RIS) impresses a…
Towards Channel Charting Enhancement with Non-Reconfigurable Intelligent Surfaces
Mahdi Maleki, Reza Agahzadeh Ayoubi, Marouan Mizmizi +1
We investigate how fully-passive electromagnetic skins (EMSs) can be engineered to enhance channel charting (CC) in dense urban environments. We employ two complementary state-of-t…
Channel Charting in Smart Radio Environments
Mahdi Maleki, Reza Agahzadeh Ayoubi, Marouan Mizmizi +1
This paper introduces the use of static electromagnetic skins (EMSs) to enable robust device localization via channel charting (CC) in realistic urban environments. We develop a ri…
Bridging the Gap via Data-Aided Sensing: Can Bistatic ISAC Converge to Genie Performance?
Musa Furkan Keskin, Silvia Mura, Marouan Mizmizi +2
We investigate data-aided iterative sensing in bistatic OFDM ISAC systems, focusing on scenarios with co-located sensing and communication receivers. To enhance target detection be…
