Query: Max-Min Fairness Design for MIMO Interference Channels: a
  Minorization-Maximization Approach   We address the problem of linear precoder (beamformer) design in a
multiple-input multiple-output interference channel (MIMO-IC). The aim is to
design the transmit covariance matrices in order to achieve max-min utility
fairness for all users. The corresponding optimization problem is non-convex
and NP-hard in general. We devise an efficient algorithm based on the
minorization-maximization (MM) technique to obtain quality solutions to this
problem. The proposed method solves a second-order cone convex program (SOCP)
at each iteration. We prove that the devised method converges to stationary
points of the problem. We also extend our algorithm to the case where there are
uncertainties in the noise covariance matrices or channel state information
(CSI). Simulation results show the effectiveness of the proposed method
compared with its main competitor.
