Secure Relay Low-Altitude Networks via Hybrid Fixed-Position and Rotatable Antenna Arrays
Maolin Li, Qi Zhang, Riqing Chen +4
The paper proposes a relay network that combines fixed-position and rotatable antenna arrays with a reconfigurable intelligent surface to enhance secure low‑altitude communications…
Enhanced Direction-Sensing Methods and Performance Analysis in Low-Altitude Wireless Network via a Rotating Antenna Array
Jinbing Jiang, Feng Shu, Minghao Chen +4
Due to the directive property of each antenna element, the received signal power can be severely attenuated when the emitter deviates from the array boresight, which will lead to a…
Rotatable Antenna-array-enhanced Direction-sensing for Low-altitude Communication Network: Method and Performance
Jinbing Jiang, Feng Shu, Bin Deng +5
In a practical multi-antenna receiver, each element of the receive antenna array has a directive antenna pattern, which is still not fully explored and investigated in academia and…
Reinforcement Learning-Based Secure Near-field Directional Modulation Enhanced by Rotatable RIS
Yongqiang Li, Feng Shu, Shaofan Chen +5
This paper investigates secure Directional Modulation (DM) design enhanced by a rotatable active Reconfigurable Intelligent Surface (RIS). In conventional RIS-assisted DM networks,…
Which Channel in 6G, Low-rank or Full-rank, more needs RIS from a Perspective of DoF?
Yongqiang Li, Feng Shu, Maolin Li +6
Reconfigurable intelligent surface (RIS), as an efficient tool to improve receive signal-to-noise ratio, extend coverage and create more spatial diversity, is viewed as a most prom…
A Two-Stage ISAC Framework for Low-Altitude Economy Based on 5G NR Signals
Haisu Wu, Hong Ren, Cunhua Pan +5
The evolution of next-generation wireless networks has spurred the vigorous development of the low-altitude economy (LAE). To support this emerging field while remaining compatible…
