Near Optimum Power Control and Precoding under Fairness Constraints in Network MIMO Systems

Figure 5

The iterative convexification procedure in Algorithm 1 is compared aginst the global optimization algorithm MAPEL in terms of execution time and achieved sum rate for a set of 50 channel realizations in a 5-cell MIMO network with power budget set to 21.6 dBm.
