Joint Discrete Precoding and RIS Optimization for RIS-Assisted MU-MIMO Communication Systems
We study the sum-rate maximization problem with the objective of finding the optimal precoding vectors and RIS configuration.
A Novel Discrete Phase Shift Design for RIS-Assisted Multi-User MIMO
Reconfigurable intelligent surface (RIS) is a newly-emerged technology that might fundamentally change how wireless networks are operated.
Optimized Precoding for MU-MIMO With Fronthaul Quantization
We also propose a heuristic low-complexity approach to quantized precoding.
Quantisation-aware Precoding for MU-MIMO with Limited-capacity Fronthaul
Base stations in 5G and beyond use advanced antenna systems (AASs), where multiple passive antenna elements and radio units are integrated into a single box.
