Figure 2From: Increasing sum-rate in large-scale cognitive radio networks by centralized power and spectrum allocationClose sum-rate performance illustration between MARL, LS-SCVX and ELCI, for a small CB system. Two adjacent cells of 100 m radius with one SU each (i.e., M=N=2), two channels (i.e., K=2), and one PU pair (i.e., L=1). Cell-based simulation using 100 random channel gain realizations.Back to article page
