Near Optimum Power Control and Precoding under Fairness Constraints in Network MIMO Systems
Figure 11
Precoding gain in SINR target selection. The figure shows that for the 2 × 4 MIMO case with a power budget 21.6 dBM, optimizing the precoder matrices allows to increase the original (without precoding) optimal SINR targets for the same power budget. This gain is more than 3 dB per user.
