Network Availability Enhancement in Low-Altitude HetNets: A Cross-Layer Design Perspective
Teng Wu, Jiandong Li, Junyu Liu +4
This paper proposes a computing-communication resource interchange method to enhance network availability (NA) in low-altitude heterogeneous networks (LA-HetNets). In these network…
Toward Security-Resilient Cell-Free Massive MIMO: A Multi-Stage Framework
Junbin Yu, Tianyu Lu, Mohammadali Mohammadi +1
This paper develops a robust security-resilient transmission framework for cell-free massive multiple-input multiple-output (CF-mMIMO) systems under active pilot spoofing attacks.…
Delay Alignment Modulation for Secure ISAC Systems
Tianyu Lu, Jiajun He, Mohammadali Mohammadi +1
This paper introduces delay-alignment modulation (DAM) for secure integrated sensing and communication (ISAC). Due to the broadcast nature of multi-user downlinks, communications a…
Resilient Cell-Free Massive MIMO Networks
Junbin Yu, Tianyu Lu, Mohammadali Mohammadi +1
This paper proposes a novel optimization framework for enhancing the security resilience of cell-free massive multiple-input multiple-output (CF-mMIMO) networks with multi-antenna…
Distributed Continuous Aperture Arrays for Multiuser SWIPT
Muhammad Zeeshan Mumtaz, Mohammadali Mohammadi, Hien Quoc Ngo +1
This paper proposes a distributed continuous aperture array (D CAPA) to support simultaneous wireless information and power transfer (SWIPT) to multiple information users (IUs) and…
Cell-Free Massive MIMO-Assisted SWIPT Using Stacked Intelligent Metasurfaces
Thien Duc Hua, Mohammadali Mohammadi, Hien Quoc Ngo +1
This study explores a next-generation multiple access (NGMA) framework for cell-free massive MIMO (CF-mMIMO) systems enhanced by stacked intelligent metasurfaces (SIMs), aiming to…
