Robust Low-Complexity WMMSE Precoding Under Imperfect CSI with Per-Antenna Power Constraints
Weighted sum-rate (WSR) maximization in downlink massive multi-user multiple-input (MU-MIMO) with per-antenna power constraints (PAPCs) and imperfect channel state information (CSI) is computationally challenging. Classical weighted minimum mean-square error (WMMSE) algorithms, in particular, have p...
