An Overview of Signal Processing Techniques for RIS/IRS-aided Wireless Systems
Cunhua Pan, Gui Zhou, Kangda Zhi +8
In the past as well as present wireless communication systems, the wireless propagation environment is regarded as an uncontrollable black box that impairs the received signal qual…
Robust Transmission Design for RIS-Aided Communications with Both Transceiver Hardware Impairments and Imperfect CSI
Zhangjie Peng, Zhiwei Chen, Cunhua Pan +2
Reconfigurable intelligent surface (RIS) or intelligent reflecting surface (IRS) has recently been envisioned as one of the most promising technologies in the future sixth-generati…
Is RIS-Aided Massive MIMO Promising with ZF Detectors and Imperfect CSI?
Kangda Zhi, Cunhua Pan, Gui Zhou +3
This paper provides a theoretical framework for understanding the performance of reconfigurable intelligent surface (RIS)-aided massive multiple-input multiple-output (MIMO) with z…
Channel Estimation with Reconfigurable Intelligent Surfaces -- A General Framework
A. Lee Swindlehurst, Gui Zhou, Rang Liu +2
Optimally extracting the advantages available from reconfigurable intelligent surfaces (RISs) in wireless communications systems requires estimation of the channels to and from the…
Channel Estimation for RIS-Aided Multiuser Millimeter-Wave Systems
Gui Zhou, Cunhua Pan, Hong Ren +2
Channel estimation in the RIS-aided massive multiuser multiple-input single-output (MU-MISO) wireless communication systems is challenging due to the passive feature of RIS and the…
