基于EMD算法的切换系列区分及时空转换参数选取仿真

摘要

As the difficulty of the current data acquisition due to the personal privacy,the data collection of mobile phone relies on the handover data platform based on a wireless communication network and integrated traffic simulation.In this paper,the EMD algorithm is used to quantify the differences of the handover sequences of different roads and the value-choosing influence of different parameters is analyzed according to the calculations of the different values of the space-time transformation parameters in the algorithm.%鉴于由于个人隐私而导致的数据获取困难问题，依托基于无线通信网络与交通集成仿真的手机切换数据平台采集手机数据，用EMD算法将不同道路切换序列的差异程度进行量化区分，根据时空转换参数ρ的不同取值得到相邻道路、不同道路之间手机切换序列对的EMD。结果表明：将EMD算法应用于不同道路序列的区分是可行的，ρ的选值不影响该算法应用的效果。
