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…
Sensing-enabled Secure Rotatable Array System Enhanced by Multi-Layer Transmitting RIS
Maolin Li, Feng Shu, Minghao Chen +4
Programmable metasurfaces and adjustable antennas are promising technologies. The security of a rotatable array system is investigated in this paper. A dual-base-station (BS) archi…
Enhanced channel estimation for near-field IRS-aided multi-user MIMO system via a large deep residual network
Yan Wang, Yongqiang Li, Minghao Chen +3
In this paper, the channel estimation (CE) of intelligent reflecting surface-aided near-field (NF) multi-user communication is investigated. Initially, the least square (LS) estima…
AI-empowered Channel Estimation for Block-based Active IRS-enhanced Hybrid-field IoT Network
Yan Wang, Feng Shu, Xianpeng Wang +4
In this paper, channel estimation (CE) for uplink hybrid-field communications involving multiple Internet of Things (IoT) devices assisted by an active intelligent reflecting surfa…
