Distributed power control vs power control game: A comparison study of performance in cognitive femtocell network

System performance on cognitive femtocell network depends on power control method. Therefore, power control comparison between DPC and PCG is needed. Result showed that DPC had higher convergence rate than PCG but maximum values of DPC was only equal to SINR target. The proposed PCG at the convergent condition was able to exceed the SINR target, yet it had higher power than the previous PCG which was unable to reach SINR target but required lower power to achieve convergent condition.
