Sensing-Assisted Secure Communication in MA-Aided ISAC: CRB Analysis and Robust Design
Yaxuan Chen, Guangchi Zhang, Miao Cui +3
A core challenge in physical-layer security is the difficulty of obtaining the channel state information (CSI) of potential eavesdroppers. The inherent sensing functionality of int…
DUGC-VRNet: Joint VR Recognition and Channel Estimation for Spatially Non-Stationary XL-MIMO
Jinhao Nie, Guangchi Zhang, Miao Cui +2
In this letter, we address spatially non-stationary near-field channel estimation for extremely large-scale multiple-input multiple-output (XL-MIMO) systems with a hybrid combining…
Enhancing User Fairness in Two-Layer RSMA: A Movable Antenna Approach
Ji Luo, Yaxuan Chen, Guangchi Zhang +3
Enhancing user fairness in advanced multi-user systems like two-layer rate-splitting multiple access (RSMA) is a critical yet challenging task. This letter proposes a novel movable…
Energy-Efficient UAV-Enabled MEC Systems: NOMA, FDMA, or TDMA Offloading?
Qingjie Wu, Miao Cui, Guangchi Zhang +3
Unmanned aerial vehicle (UAV)-enabled mobile edge computing (MEC) systems can use different multiple access schemes to coordinate multi-user task offloading. However, it is still u…
AN-Aided Secure Beamforming for ELAA-SWIPT in Mixed Near- and Far-Field
Yaqian Yi, Guangchi Zhang, Miao Cui +2
This letter investigates secure hybrid beamforming (HB) design for an extremely large-scale antenna array-aided simultaneous wireless information and power transfer (SWIPT) system…
Near-Field Codebook-Based 3D Spherical Channel Estimation for UCA XL-MIMO Systems
Chenliang Yang, Guangchi Zhang, Miao Cui +2
Extremely large-scale multiple input multiple output (XL-MIMO), a key technology for 6G communications, faces challenges in near-field channel estimation due to spherical wavefront…
