Secure Directional Modulation Enabled by Elevatable and Rotatable Antenna Array for Maritime Communications
Maolin Li, Haini Wu, Feng Shu +3
To address the dual challenges of limited transmission distance and wireless communication security in maritime communications, a directional modulation network enhanced by an elev…
Secure Relay Low-Altitude Networks via Hybrid Fixed-Position and Rotatable Antenna Arrays
Maolin Li, Qi Zhang, Minghao Chen +6
In this paper, a relay network with hybrid fixed-position and rotatable antenna arrays is proposed. The deployment of rotatable arrays in conventional relay networks is considered…
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,…
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…
