Intelligent Reflecting Surface Deployment for Low-Altitude Coverage: Illumination Geometry, Directional Characteristics, and Optimization
Guoying Zhang, Qingqing Wu, Ailing Zheng +3
Terrestrial base stations (BSs) are typically configured with fixed downtilt to serve ground users, resulting in weak illumination of low-altitude airspace even under line-of-sight…
Joint Transmit and Receive Antenna Orientation Design for Secure MIMO Communications
Ailing Zheng, Qingqing Wu, Xingxiang Peng +4
Physical layer security (PLS) is a promising paradigm for safeguarding 6G wireless networks by exploiting the inherent characteristics of wireless channels. However, the efficiency…
Joint Transceiver Orientation Optimization for Rotatable-Antenna MIMO Capacity Maximization
Zheng Ailing, Wu Qingqing, Peng Xingxiang +3
Conventional multiple-input multiple-output (MIMO) systems mainly rely on fixed antenna arrays, which limits their capability to adapt the effective channel matrix to the propagati…
Secrecy Sum-Rate Maximization for Active IRS-Assisted MIMO-OFDM SWIPT System
Xingxiang Peng, Peiran Wu, Junhui Zhao +1
The propagation loss of RF signals is a significant issue in simultaneous wireless information and power transfer (SWIPT) systems. Additionally, ensuring information security is cr…
