摘要:

本文提出了分析和经验数据记录在60 GHz频段的太阳射电辐射对室外传播路径损耗的影响。视线(LOS)和非LOS的情况下被认为是。实证研究中使用的设置模拟了未来第五代蜂窝系统的接入和回程服务,以及设备到设备通信。基于在太阳活动强烈的晴朗天气下收集的测量数据,建立了60 GHz大尺度传播路径损耗模型,并观测了太阳射电辐射对路径损耗数据的影响。结果表明,太阳射电辐射可以降低载噪比,这转化为相应的大规模传播路径损耗信道模型的路径损耗指数(PLE)值的增加。实验数据表明,白天(41° ~ 42 °C)炎热晴朗天气下的PLE值比夜间(20° ~ 38 °C)凉爽晴朗天气下的PLE值高9.0%~ 15.6%。这意味着在白天炎热和阳光明媚的天气中,60 GHz无线电覆盖范围相应减少。所提出的分析估计数密切证实了经验数据。

英文摘要:

This paper presents analytical and empirical data documenting the effects of solar radio emissions on outdoor propagation path loss at 60 GHz bands. Both line-of-sight (LOS) and non-LOS scenarios were considered. The setup used in the empirical studies emulates the future fifth-generation cellular systems for both access and backhaul services, as well as for device-to-device communications. Based on the measurement data collected in sunny weather with intense solar activities, we developed large-scale propagation path loss models at 60 GHz, and observed the effects of solar radio emissions on the path loss data. It is shown that solar radio emission can decrease carrier-to-noise ratio, and that this translates into a corresponding increase in the path loss exponent (PLE) values for the large-scale propagation path loss channel models. Empirical data show that 9.0%-15.6% higher PLE values were observed in hot and sunny weather during the day (41°-42 °C) compared with the counterpart measurements taken at night in cool and clear weather (20°-38 °C). This translates into a corresponding decrease in 60 GHz radio coverage in hot and sunny weather during the day. The empirical data are closely corroborated by analytical estimates presented.
