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…
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…
