RIS-Assisted Multiuser NOMA Networks With Imperfect CSI Under Transceiver Hardware Impairments
Qian Zhang, Maoyuan Wang, Xuejun Cheng +3
The incorporation of non-orthogonal multiple access (NOMA) and reconfigurable intelligent surface (RIS) provides a new solution to improve spectral efficiency. Unfortunately, the c…

Joint Precoding and Phase-Shift Optimization for Beyond-Diagonal RIS-Aided ISAC System
Xuejun Cheng, Qian Zhang, Yuhui Jiao +4
Beyond diagonal reconfigurable intelligent surfaces (BD-RIS) can realize the interconnection between reflecting elements through the impedance network, thereby providing a new appr…
