摘要
通过对抽样调查理论和无线传播特点的研究,提出了一种移动通信网络路测数据的抽样与分析方法。首先根据抽样理论,引入聚类分析进行分类,采用整群抽样和二阶段抽样,给出了分析路测数据的方法。为了提高路测采集数据的有效性,以根据抽样理论确定的抽样点数目作为指导,结合无线网络规划理论,提出了有效的路测路线确定方法。
By the research of sampling survey and radio propagation, a novel method on sampling and analysis of field test data is introduced. According to the theory of sampling survey, cluster analysis is introduced to finish the sort. Then a method on analysis of field test is presented by using cluster sawpling and two-stage sawpiing. In order to improve the reliability of field test data, by the estimation theory of sample size, a method of field test route choice is introduced based on wireless network planning.
