TD-SCDMA室内规划仿真中的快速分析

根据DoCoMo的最新统计,室内场所吸收了将近70%的话务量.因此室内覆盖对于3G网络的建设具有至关重要的作用.TD-SCDMA网络推出在即,网络规划方法在网络建设中具有极其重要的作用.考虑到如果引入复杂的计算,将不得不要求用户创建各种相关模型,输入步骤过于繁琐.通过对TD-SCDMA网络及其规划方法的研究提出了快速分析方法.采用简化的Keenan-Motley方法计算路径损耗从而进行快速分析.对于下行分析,可以计算下行的EcIo从而生成导频覆盖图.对于上行分析,能给出各终端的发射功率从而产生报表输出.

Insight TD-SCDMA cover analysis

According to the latest statistics of the DoCoMo,almost 70 percents of the traffic volume was absorbed by indoor circumstance. Therefore,indoor coverage is very important in the construction of the 3G network. TD-SCDMA is about to be published,so the network planning plays a indispensable role in network construction. If importing complex calculation,users will have to establish all kinds of relevant models with fussy input process. A fast solution is presented through the study of TD-SCDMA network and planning. We adopt simplified Keenan-Motley model to calculate path loss so as to fasten the analysis. For down-link,this algorithm can calculate down link Ec/Io and generate pilot covering graph,while for up-link,it can calculate the sending power consumption of each terminal and to generate report output.
