Cell-Free Massive MIMO for Joint Communication and Proactive Monitoring
Mustafa S. Abbas, Zahra Mobini, Hamid Reza Hashempour +2
This paper introduces a novel joint communication and proactive monitoring (JCAM) system that simultaneously monitors multiple untrusted links and serves multiple legitimate users.…
Anti-Malicious ISAC: How to Jointly Monitor and Disrupt Your Foes?
Zonghan Wang, Zahra Mobini, Hien Quoc Ngo +2
Integrated sensing and communication (ISAC) systems are key enablers of future networks but raise significant security concerns. In this realm, the emergence of malicious ISAC syst…
Robust Energy-Efficient Sleep-Mode Strategy for Multi-RIS-Aided Cell-Free Massive MIMO
Hongyi Luo, Wenyu Song, Daniel K. C. So +2
With the explosive growth of data traffic and the ubiquitous connectivity of wireless devices, the energy demands of wireless networks have inevitably escalated. Reconfigurable int…
Cluster-wise processing in fronthaul-aware cell-free massive MIMO systems
Zahra Mobini, Ahmet Hasim Gokceoglu, Li Wang +3
We exploit a general cluster-based network architecture for a fronthaul-limited user-centric cell-free massive multiple-input multiple-output (CF-mMIMO) system under different degr…
Hybrid centralized-distributed precoding in fronthaul-constrained CF-mMIMO systems
Zahra Mobini, Hien Quoc Ngo, Ardavan Rahimian +4
We investigate a fronthaul-limited cell-free massive multiple-input multiple-output (CF-mMIMO) system and propose a hybrid centralized-distributed precoding strategy that dynamical…
Cell-Free Massive MIMO-Based Physical-Layer Authentication
Isabella W. G. da Silva, Zahra Mobini, Hien Quoc Ngo +1
In this paper, we exploit the cell-free massive multiple-input multiple-output (CF-mMIMO) architecture to design a physical-layer authentication (PLA) framework that can simultaneo…
