宽带码分多址导频污染分析及优化策略

WCDMA Pilot Pollution Analysis and Optimization Strategy

在宽带码分多址系统室内分布设计中,导频污染问题是不可避免的,导频问题的存在容易造成频繁切换,导致掉话,影响网络性能和网络质量.文章首先分析导频污染产生的具体原因,根据实际情况再给出导频污染的解决方法,优化宽带码分多址网络中出现的导频污染或者覆盖空洞.

In WCDMA system interior distribution design, pilot pollution problem is inevitable, pilot problems can easily cause the frequent switching, lead to drop the words, affects the performance of network and the network quality. Analysis of the pilot pollution specific reasons, according to the actual situation and then presents pilot pol- lution solution, optimization of the pilot pollution or cover empty appeared in the WCDMA network.
