Cross-Band Movable-Antenna Communications under Frequency-Dependent Multipath
Guangchen Wang, Zhifeng Tang, Haiyao Yu +3
Movable antennas (MAs) provide additional spatial degrees of freedom by adapting their physical positions to the propagation environment. However, existing studies mainly focus on…
QoE-Driven Hybrid Resource Allocation for Multi-User OFDMA Semantic Communications
Xiaotian Xu, Zhifeng Tang, Guangchen Wang +4
In this paper, we develop a quality-of-experience (QoE)-driven hybrid resource allocation framework for multi-user downlink orthogonal frequency-division multiple access semantic c…
Artificial-Noise Aided Design for Movable-Antenna Enabled Physical-Layer Service Integration
Zhifeng Tang, Guangchen Wang, Nan Yang +2
This paper pioneers a novel scheme for artificial-noise (AN)-aided movable-antenna (MA)-enabled physical-layer service integration (PLSI) to harmonize the simultaneous delivery of…
Impact of Pointing Errors and Correlated Wall Blockages on Practical Grid-based Indoor Terahertz Communication Systems
Zhifeng Tang, Nan Yang, Salman Durrani +3
Terahertz (THz) communications has emerged as a promising technology for future wireless systems due to its potential to support extremely high data rates. However, severe path los…
Impact of Pointing Error on Coverage Performance of 3D Indoor Terahertz Communication Systems
Zhifeng Tang, Nan Yang, Xiangyun Zhou +3
In this paper, we develop a tractable analytical framework for a three-dimensional (3D) indoor terahertz (THz) communication system to theoretically assess the impact of the pointi…
Near-Field Secure Beamfocusing With Receiver-Centered Protected Zone
Cen Liu, Xiangyun Zhou, Nan Yang +2
This work studies near-field secure communications through transmit beamfocusing. We examine the benefit of having a protected eavesdropper-free zone around the legitimate receiver…
