Multi-Carrier Modulation: An Evolution from Time-Frequency Domain to Delay-Doppler Domain
Hai Lin, Jinhong Yuan, Wei Yu +2
The recently proposed orthogonal delay-Doppler division multiplexing (ODDM) modulation, which is a delay-Doppler (DD) domain multi-carrier (DDMC) modulation scheme based on the DD…
Improved Differential Evolution for Enhancing the Aggregated Channel Estimation of RIS-Aided Cell-Free Massive MIMO
Trinh Van Chien, Nguyen Hoang Viet, Symeon Chatzinotas +1
Cell-Free Massive multiple-input multiple-output (MIMO) systems are investigated with the support of a reconfigurable intelligent surface (RIS). The RIS phase shifts are designed f…
Joint Access Point Activation and Power Allocation for Cell-Free Massive MIMO Aided ISAC Systems
Nguyen Xuan Tung, Le Tung Giang, Trinh Van Chien +2
Cell-free massive multiple-input multiple-output (MIMO)-aided integrated sensing and communication (ISAC) systems are investigated where distributed access points jointly serve use…
Hybrid Quantum Convolutional Neural Network-Aided Pilot Assignment in Cell-Free Massive MIMO Systems
Doan Hieu Nguyen, Xuan Tung Nguyen, Seon-Geun Jeong +3
A sophisticated hybrid quantum convolutional neural network (HQCNN) is conceived for handling the pilot assignment task in cell-free massive MIMO systems, while maximizing the tota…
Cell-Free Massive MIMO Surveillance of Multiple Untrusted Communication Links
Zahra Mobini, Hien Quoc Ngo, Michail Matthaiou +1
A cell-free massive multiple-input multiple-output (CF-mMIMO) system is considered for enhancing the monitoring performance of wireless surveillance, where a large number of distri…
Ergodic Spectral Efficiency Analysis of Intelligent Omni-Surface Aided Systems Suffering From Imperfect CSI and Hardware Impairments
Qingchao Li, Mohammed El-Hajjar, Lajos Hanzo
In contrast to the conventional reconfigurable intelligent surfaces (RIS), intelligent omni-surfaces (IOS) are capable of full-space coverage of smart radio environments by simulta…
