Mooyoung Lee, Do-Chang Oh, Woo-Hyen Kwon · 2006 SICE-ICASE International Joint Conference · 2006
The current paper presents a power control method with variable state feedback gain (VFPC) to improve outage convergence rate of distributed constrained power control. The variable state feedback gain includes the information of the desired SIR changes and must be a decreasing sequence for the convergence and the proof for the convergence is given. The proposed algorithm in this paper can be improved the outage convergence rate and SIR (signal to interference ratio) response at the both start time and the steady state when SIR changes are occurred. The simulation results are given
