Weighted MMSE Optimization of Conjugate Beamforming for Cell-Free Massive MIMO
2021 Twelfth International Conference on Ubiquitous and Future Networks (ICUFN)（2021）
摘要
Cell-free massive multiple-input multiple-output (MIMO) systems are envisioned to achieve the improved spectral efficiency by supporting users via nearby access points (APs). This work addresses the optimization of beamforming weights for cell-free massive MIMO systems. The connectivity level constraints are taken into account to accommodate finite-rate fronthaul links. The minimum rate maximizati...
