Error Propagation and Overhead Reduced Channel Estimation for RIS-Aided Multi-User mmWave Systems
Zhendong Peng, Cunhua Pan, Gui Zhou +1
In this paper, we propose a novel two-stage based uplink channel estimation strategy with reduced pilot overhead and error propagation for a reconfigurable intelligent surface (RIS…
Joint Angle Estimation Error Analysis and 3D Positioning Algorithm Design for mmWave Positioning System
Tuo Wu, Cunhua Pan, Yijin Pan +5
In this paper, we propose a comprehensive framework to jointly analyze the angle estimation error and design the three-dimensional (3D) positioning algorithm for a millimeter wave…
Active RIS Versus Passive RIS: Which Is Superior with the Same Power Budget?
Kangda Zhi, Cunhua Pan, Hong Ren +2
This letter theoretically compares the active reconfigurable intelligent surface (RIS)-aided system with the passive RIS-aided system. For fair comparison, we consider that these t…
RIS-Aided D2D Communications Relying on Statistical CSI with Imperfect Hardware
Zhangjie Peng, Tianshu Li, Cunhua Pan +2
In this letter, we investigate a reconfigurable intelligent surfaces (RIS)-aided device to device (D2D) communication system over Rician fading channels with imperfect hardware inc…
