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…
Joint Power Splitting and Secure Beamforming Design in the Wireless-powered Untrusted Relay Networks
Mingxiong Zhao, Suili Feng, Yuan Liu +3
In this work, we maximize the secrecy rate of the wireless-powered untrusted relay network by jointly designing power splitting (PS) ratio and relay beamforming with the proposed g…
