摘要 基于降雨衰减时间序列合成方法,模拟产生了北京地区28 GHz、30 GHz和38 GHz的动态降雨衰减时间序列,并应用快速傅里叶变换和Kaiser窗函数对其功率谱进行估计。多次模拟降雨衰减事件,并对模拟序列进行统计分析,得到降雨衰减的概率分布,并与ITU-R推荐的模型进行比较。本文方法可用于5G通信网络链路的降雨衰减预测和性能分析研究。 Based on the synthetic method of rainfall attenuation time series,the dynamic rainfall attenuation time series at 28 GHz、30 GHz and 38 GHz in Beijing are simulated,and the power spectraare estimated by using fast Fourier transform and Kaiser Window function.The probability distributions of rainfall attenuation are obtained by simulating rainfall attenuation events for many times and statistical analyzing of the simulation series.Compared with the model recommended by ITU-R,it can be used for the prediction of 5G millimeter wave rainfall attenuation.
