Robust Beamforming and Power Allocation for Coherent Cell-Free Massive MIMO with Residual Calibration Errors
A time-evolving RCE model is developed that characterizes the joint effects of residual phase mismatches, residual carrier frequency offsets, and oscillator phase noise, and a Gauss--Legendre quadrature-based weighted minimum mean square error (WMMSE) optimization framework is developed.
