摘要在3G移动通信网络中,天线的覆盖范围对通信质量有很大的影响,天线的覆盖范围主要由基站的分布和基站上天线的工程参数决定。这些工参在最初测量时可能存在误差,此外,由于自然因素的影响,工参会随时间而变化。因此,每隔一段时间就需要核查基站工程参数的记录数据与实际值是否一致。63684

Title The Check of 3G Base Station Engineering Parameters
Abstract In the networks of 3G mobile communication, the coverage of antennas may greatly influence communication quality. Antenna coverage is mainly determined by the position of the base station and the engineering parameters. There may be deviation between the true values and the recorded ones because of the faults when measuring these parameters. In addition, the changes of the environment may also cause these deviations. Therefore, we need to check whether the true and recorded values are the same at set intervals.
With the MR data reported by mobile stations like mobile phones, this thesis presents some algorithms to estimate the position, azimuth and downtilt of the antenna.Based on these algorithms, I estimated the parameters of some antennas which have enough data for estimation.In order to avoid processing large amounts of data and writing programs, I designed a software based on Matlab/GUI to estimate antenna parameters. This software can also help users who do not understand the algorithms deeply.
