Joint MIMO Transceiver and Reflector Design for Reconfigurable Intelligent Surface-Assisted Communication
Yaqiong Zhao, Jindan Xu, Wei Xu +4
In this paper, we consider a reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output communication system with multiple antennas at both the base station (…
Cooperative Reflection and Synchronization Design for Distributed Multiple-RIS Communications
Yaqiong Zhao, Wei Xu, Xiaohu You +2
To reap the promised gain achieved by distributed reconfigurable intelligent surfaces (RISs)-enhanced communications in a wireless network, timing synchronization among these metas…
Cooperative Reflection Design with Timing Offsets in Distributed Multi-RIS Communications
Yaqiong Zhao, Wei Xu, Huan Sun +2
This letter investigates a wireless communication system deploying distributed reconfigurable intelligent surfaces (RISs). Existing works have assumed that perfect timing synchroni…
Analog Versus Hybrid Precoding for Multiuser Massive MIMO with Quantized CSI Feedback
Yaqiong Zhao, Wei Xu, Jindan Xu +3
In this letter, we study the performance of a downlink multiuser massive multiple-input multiple-output (MIMO) system with sub-connected structure over limited feedback channels. T…
