摘　　要：在HSPA系统中,实现高精度的快速闭环功率控制的基础是信干比(SIR)的精确测量。本文在对Shunsuke所提SIR估计算法性能分析的基础上提出了几种优化方案,并通过仿真进行了性能分析,结果表明优化方案不仅对原算法的抖动性有了很好的改善,而且能够明显的加快收敛速度。In the HSPA system, to achieve high -precision fast closed -loop power control is based on the signal to interference ratio （SIR） for accurate measurement. In this paper, Shunsuke proposed SIR estimation algorithm for performance analysis based on the optimization of several programs, and conducted a performance analysis through simulation results show that the optimal scheme is not only the jitter of the original algorithm has a very good improvement, but also can significantly the acceleration of convergence speed.
