Second-order Fast Convergence Distributed Power Control for TD-SCDMA
Yuan-Yuan Jin · China Information Security · 2007
Unitary power control based on Signal-to-Interference Ratio (SIR) measurement has been widely used in cellular radio system. In this paper, we proposed a second-order fast convergence distributed power control algorithm based on SIR measurement. Applying iterative method for power updating, this algorithm uses both current power level and previous power level to adjust transmission power. Through the analyses of simulation and computational experiments that carried out, we has found that in same spreading condition, the proposed power control algorithm has faster convergence than DPC and SOPC.
