摘要

采用多台发射机和一台接收机的协作通信技术，可以大大提高通信系统的性能。事实上，从第四代移动通信系统开始，协作通信就已经开始了。两种相互竞争的合作技术是;继电器和智能反射面(IRS)。众所周知，电磁干扰(EMI)会降低无线电系统的性能。本文对电磁干扰的影响进行了数学建模和仿真。干扰水平会受到信道参数的影响，信道参数是5G路径损耗模型。为了提高通信系统的性能，采用了Alamouti码。由分集码“Alamouti”提供的增益可以减少由于电磁干扰的存在而导致的性能下降。建立了完整的数学模型和仿真模型。仿真结果表明，在EMI存在的情况下，协作的alamouti编码5G无线电系统仍具有令人满意的性能。

Study of Electromagnetic Interference Effects in Intelligent Reflecting Surfaces Aided Communication in Alamouti Coded 5G Networks

: The cooperative communication techniques, wherein several transmitters and one receiver are implemented, can greatly increase the performance of a communication system. In fact, the cooperative communication has been launched since the fourth generation mobile systems. The two competing cooperative techniques are; relays and intelligent reflecting surfaces (IRS). It is known that the electromagnetic interference (EMI) can degrade a radio system performance. In this paper, the EMI, affecting an IRS-based communication system, is mathematically modeled and simulated. The interference level can be affected by the channel parameters which are the 5G path loss models. In order to improve the communication system performance, Alamouti codes are applied. The gain, offered by diversity codes “Alamouti”, can reduce the degradation of the performance due to the EMI existence. The complete mathematical model is carried out as well as the simulation model. The simulation results show that the cooperative Alamouti-coded 5G radio systems have a satisfying performance even the EMI exists.

期刊介绍： The International Journal of Interdisciplinary Telecommunications and Networking (IJITN) examines timely and important telecommunications and networking issues, problems, and solutions from a multidimensional, interdisciplinary perspective for researchers and practitioners. IJITN emphasizes the cross-disciplinary viewpoints of electrical engineering, computer science, information technology, operations research, business administration, economics, sociology, and law. The journal publishes theoretical and empirical research findings, case studies, and surveys, as well as the opinions of leaders and experts in the field. The journal''s coverage of telecommunications and networking is broad, ranging from cutting edge research to practical implementations. Published articles must be from an interdisciplinary, rather than a narrow, discipline-specific viewpoint. The context may be industry-wide, organizational, individual user, or societal. Topics Covered: -Emerging telecommunications and networking technologies -Global telecommunications industry business modeling and analysis -Network management and security -New telecommunications applications, products, and services -Social and societal aspects of telecommunications and networking -Standards and standardization issues for telecommunications and networking -Strategic telecommunications management -Telecommunications and networking cultural issues and education -Telecommunications and networking hardware and software design -Telecommunications investments and new ventures -Telecommunications network modeling and design -Telecommunications regulation and policy issues -Telecommunications systems economics
