Performance comparison of distributed power control algorithms in cellular radio systems

Power control is a key technique in cellular radio systems. Convergence rate and energy efficiency are two important factors to evaluate power control algorithms. This paper presents a comparative analysis of various distributed power control algorithms in feasible systems. The results of analysis and simulation show that CPIPC and CSOPC offer the advantage of faster convergence, while GDCPC and CSOPC consume less power than other algorithms. Consequently in consideration of both convergence rate and energy efficiency, it is concluded that CSOPC offers the best performance.
