Subverting Flexible Multiuser Communications via Movable Antenna-Enabled Jammer
Guojie Hu, Qingqing Wu, Lipeng Zhu +5
Movable antenna (MA) is an emerging technology which can reconfigure wireless channels via adaptive antenna position adjustments at transceivers, thereby bringing additional spatia…
Ergodic Capacity of High Throughput Satellite Systems With Mixed FSO-RF Transmission
Kong Huaicong, Lin Min, Wang Zining +2
We study a high throughput satellite system, where the feeder link uses free-space optical (FSO) and the user link uses radio frequency (RF) communication. In particular, we first…
Robust Beamforming for Enhancing Security in Multibeam Satellite Systems
Jian Zhang, Min Lin, Jian Ouyang +2
This paper proposes a robust beamforming (BF) scheme to enhance physical layer security (PLS) of the downlink of a multibeam satellite system in the presence of either uncoordinate…
Secrecy Energy Efficiency Optimization for Artificial Noise Aided Physical-Layer Security in OFDM-Based Cognitive Radio Networks
Yuhan Jiang, Yulong Zou, Jian Ouyang +1
In this paper, we investigate the power allocation of primary base station (PBS) and cognitive base station (CBS) across different orthogonal frequency division multiplexing (OFDM)…
