中文摘要：
基于信号干扰比（SIR）测量的归-化功率控制在无线蜂窝系统中有着广泛的应用。论文提出TD—SCDMA系统中的基于SIR测量的二阶快速收敛分布式功率控制算法，使用当前功率和前次功率共同参与运算控制移动台发射功率。仿真结果表明，论文提出的二阶快速收敛DPC算法在相同的传播环境下比DPC和SOPC具有更快的收敛速度。
英文摘要：
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.
