摘要
为了有效的提高WCDMA的效率,在功率控制的基础上,通过分析WCDMA功率控制的实现方法,提出一种基于SIR的分布式闭环功率控制方法.再与DM算法作了比较对其进行了仿真试验,证实了该算法对信道变化可以做出快速反应并具有较强的抗干扰能力,同时使SIR具有较好的收敛性,可以有效的提高其效率.
In order to improve the WCDMA efficiency effectively, we analyse andalyse the method of carrying out of WCDMA power control based on the power control in this paper, and bring forward a distributional closed- loop power control method based on SIR. We carry on the simulation experiments, then compare with DM algo- rithm, the results confirmed that the algorithm can make the rapid reaction to the channel changes with a strong anti-jamming capability, and make SIR have a better astringency, show that this method can effectively improve its efficiency and the advantages of this method being significant.
