Figure 2From: Joint resource allocations for remote radio head deployments with coherent transmitterComparisons of spectrum efficiency (SE) between proportional power allocation (PPA) and full power allocation. Figure 2 shows the spectrum efficiency (bps/Hz) of proportional power allocation (PPA) and full power allocation versus different RRH port numbers. Legend of curves from top to bottom: Full power allocation; Proportional power allocation.Back to article page
