摘　　要：第五代移动通信技术采用毫米波多输入多输出天线为高质量无线通信提供技术支撑,对传统的辐射安全性评估带来新的挑战。提出了采用无监督深度学习方法,分析毫米波MIMO设备电磁辐射上限,进而实现对MIMO设备辐射安全性的评估。首先从理论上分析了利用无监督学习方法分析MIMO设备电磁辐射上限的可行性,并以工作频率28 GHz的不同天线阵列为例,验证所提方法的可行性。此外,利用蒙特卡洛法作为参照对比验证了所提算法的可靠性。结果表明,所提方法与蒙特卡洛法的功率密度分布最大值和均值的误差均可控制在0.07%以下,可以准确高效地分析毫米波MIMO设备辐射上限,为快速评估毫米波MIMO设备的辐射安全性提供了新的方案。The fifth generation mobile communication technology uses millimeter wave Multiple-Input Multiple-Output antenna to provide technical support for high quality wireless communication,which brings new challenges to traditional radiation safety assessment.This paper proposes an unsupervised deep learning method to analyze the upper limit of electromagnetic radiation of millimeter wave MIMO equipment,and then evaluate the radiation safety of MIMO equipment.This paper first theoretically analyzes the feasibility of using unsupervised learning methods to analyze the upper limit of electromagnetic radiation of MIMO devices,and takes different antenna arrays with operating frequencies of 28 GHz as examples to verify the feasibility of the proposed method.In addition,the reliability of the proposed algorithm was verified by Monte Carlo method as a reference.The results show that the error of the maximum and mean values of the power density distribution between the proposed method and Monte Carlo method can be controlled below 0.07%.The proposed method can accurately and efficiently analyze the radiation upper limit of the millimeter wave MIMO equipment,which provides a new scheme for rapid evaluation of the radiation safety of millimeter wave MIMO equipment.
