摘要
CDMA系统是干扰受限的系统,降低干扰可以提高系统的容量。TD—SCDMA系统的功率控制就是在保证用户的QoS前提下,降低发射功率,减少系统干扰从而增大系统的容量。本文介绍了TD—SCDMA中外环空率控制的算法,并且分析了功率控制参数对系统性能的影响。
CDMA is a system that is influenced by interferences, so its capacity can he increased by lessening the system interference. In riD -SCDMA, the power control is to decrease the transmition power and lessen the interference to largen the system capacity. The outer -loop power control algorithm in TD -SCDMA is introduced and the power control parameters to influence the system performance are analyzed in this paper.
