5G的超低时延和超快传输速率给人们的生活带来了巨大变化。5G的FR1(Sub-6 GHz)频段周围无线电业务众多，受到的干扰愈发明显，超宽带(Ultra Wide-Band, UWB)信号就是其中之一。UWB频段和5G频段部分共用，UWB信号会对5G信号解调带来严重影响，所以5G与UWB之间的同频干扰研究尤为重要。基于Matlab和Simulink联合链路级仿真实现了UWB信号对5G信号的同频干扰研究，并通过暗室实测分析了UWB信号对5G的干扰。仿真和实测都证实了5G信号在距离较近时会受到同频UWB信号的干扰，但是距离大于0.4 m的情况下，5G受到的干扰已经不明显。所提方法和实测结论为5G和UWB信号共存提供了基础数据。
Abstract：The ultra-low latency and ultra-fast transmission rate of 5 G have brought tremendous changes to people's lives.Due to huge radio services around 5 G FR1(Sub-6 GHz),the interference becomes more and more obvious, and the Ultra Wide-Band(UWB) signal is one of them.Since the UWB frequency band and the 5 G frequency band are partially shared, the UWB signal will have a serious impact on the demodulation of 5 G signal.Hence, the research on co-channel interference between 5 G and UWB is particularly important.Based on Matlab and Simulink joint link-level simulation, the co-channel interference research of UWB signal to 5 G signal is realized.And the interference of UWB signal to 5 G is analyzed in an anechoic chamber.Both the simulations and actual measurements have confirmed that 5 G signal will be interfered by the co-channel UWB signal when their distance is relatively close.But when the distance is greater than 0.4 m, the interference of UWB to 5 G is not obvious.The research methods and experiment conclusions provide basic data for 5 G and UWB signal coexistence.
