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…
Two-Stage Hybrid Transceiver Design Relying on Low-Resolution ADCs in Partially Connected MU Terahertz (THz) MIMO Systems
Abhisha Garg, Akash Kumar, Suraj Srivastava +2
A two-stage hybrid transceiver is designed by considering a partially connected architecture at the base station (BS) for a low-resolution multi-user (MU) THz massive multiple inpu…
Towards Global Quantum Key Distribution
Haoran Zhang, Haotao Zhu, Ruihua He +4
Quantum Key Distribution (QKD) supports the negotiation and sharing of private keys with unconditional security between authorized parties. Over the years, theoretical advances and…
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…
