Artificial Noise Versus Artificial Noise Elimination: Redefining Scaling Laws of Physical Layer Security
Hong Niu, Tuo Wu, Xia Lei +4
Artificial noise (AN) is a key physical-layer security scheme for wireless communications over multiple-input multiple-output wiretap channels. Recently, artificial noise eliminati…
Movable Antenna-Aided Hybrid Beamforming for Multi-User Communications
Yichi Zhang, Yuchen Zhang, Lipeng Zhu +4
In this correspondence, we propose a movable antenna (MA)-aided multi-user hybrid beamforming scheme with a sub-connected structure, where multiple movable sub-arrays can independe…
Robust Transceiver Design for Covert Integrated Sensing and Communications With Imperfect CSI
Yuchen Zhang, Wanli Ni, Jianquan Wang +4
We propose a robust transceiver design for a covert integrated sensing and communications (ISAC) system with imperfect channel state information (CSI). Considering both bounded and…
Energy-Efficient UAV Communications: A Generalised Propulsion Energy Consumption Model
Xinhong Dai, Bin Duo, Xiaojun Yuan +1
This paper proposes a generalised propulsion energy consumption model (PECM) for rotary-wing ummanned aerial vehicles (UAVs) under the consideration of the practical thrust-to-weig…
Performance Analysis for Covert Communications Under Faster-than-Nyquist Signaling
Yuan Li, Yuchen Zhang, Wanyu Xiang +4
In this letter, we analyze the performance of covert communications under faster-than-Nyquist (FTN) signaling in the Rayleigh block fading channel. Both Bayesian criterion- and Kul…
UAV-Enabled Cooperative Jamming for Covert Communications
Hangmei Rao, Sa Xiao, Shihao Yan +2
This work employs an unmanned aerial vehicle (UAV) as a jammer to aid a covert communication from a transmitter Alice to a receiver Bob, where the UAV transmits artificial noise (A…
Estimating the Distance Between Macro Base Station and Users in Heterogeneous Networks
Lin Zhang, Wenli Zhou, Wanbin Tang +2
In underlay heterogeneous networks (HetNets), the distance between a macro base station (MBS) and a macro user (MU) is crucial for a small-cell based station (SBS) to control the i…
