Cell-Free Full-Duplex Communication -- An Overview
Diluka Galappaththige, Mohammadali Mohammadi, Hien Quoc Ngo +2
Cell-free (CF) architecture and full-duplex (FD) communication are leading candidates for next-generation wireless networks. The CF framework removes cell boundaries in traditional…
Differential Evolution-Based End-Fire Realized Gain Optimization of Active and Parasitic Arrays
Rozita Konstantinou, Ihsan Kanbaz, Okan Yurduseven +1
We propose a novel approach for boosting the realized gain in enhanced directivity arrays with both active and parasitic dipoles as radiating elements. The optimization process inv…
Anti-Malicious ISAC Using Proactive Monitoring
Zonghan Wang, Zahra Mobini, Hien Quoc Ngo +1
In this paper, we investigate proactive monitoring to mitigate malicious activities in integrated sensing and communication (ISAC) systems. Our focus is on a scenario where a cell-…
Unicast-Multicast Cell-Free Massive MIMO: Gradient-Based Resource Allocation
Mustafa S. Abbas, Zahra Mobini, Hien Quoc Ngo +1
We consider a cell-free massive multiple-input multiple-output (CF-mMIMO) system with joint unicast and multi-group multicast transmissions. We derive exact closed-form expressions…
CSI Acquisition in Cell-Free Massive MIMO Surveillance Systems
Isabella W. G. da Silva, Zahra Mobini, Hien Quoc Ngo +1
We consider a cell-free massive multiple-input multiple-output (CF-mMIMO) surveillance system, in which multiple multi-antenna monitoring nodes (MNs) are deployed in either observi…
Analysis of Cross-Domain Message Passing for OTFS Transmissions
Ruoxi Chong, Shuangyang Li, Zhiqiang Wei +3
In this paper, we investigate the performance of the cross-domain iterative detection (CDID) framework with orthogonal time frequency space (OTFS) modulation, where two distinct CD…
