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…
Multi-Branch DNN and CRLB-Ratio-Weight Fusion for Enhanced DOA Sensing via a Massive HAD MIMO Receiver
Feng Shu, Jiatong Bai, Di Wu +4
As a green MIMO structure, massive HAD is viewed as a potential technology for the future 6G wireless network. For such a structure, it is a challenging task to design a low-co…
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…
Two Efficient Beamforming Methods for Hybrid IRS-aided AF Relay Wireless Networks
Xuehui Wang, Feng Shu, Mengxing Huang +5
Due to the double fading effect caused by conventional passive intelligent reflecting surface (IRS), the signal via the reflection link is weak. To enhance the received signal, act…
