传播模型构成了无线通信研究的基本组成部分。在我们构建和操作真实的系统之前，我们必须了解无线电传播的科学，并开发既能反映重要传播过程又能对不同系统进行公平比较的信道模型。在过去的五十年中，无线系统已经经历了五代，从支持语音应用到增强型移动的宽带。为了满足无线系统不断增长的数据速率需求，已经分配了覆盖从800 MHz到100 GHz的宽范围的频带以供使用。随着全球移动的通信系统的出现，这些系统的标准化在20世纪80年代早期/中期由欧洲电信标准协会在欧洲开始。这促使欧洲科学技术合作（COST）207工作组开发了第一个标准化传播模型。这些标准化活动在COST的第三、第四和第五代以及第三代合作伙伴项目和国际数字通信联盟中得到了继续和扩大。本文提出了一个历史的概述，标准化的传播模型，涵盖第一至第五代系统。特别是，我们讨论了路径损耗模型的演变和标准化，以及单天线和多天线系统的大尺度和小尺度衰落参数。此外，我们提出的见解确定性建模的进展，在五代系统，以及讨论更先进的建模组件所需的毫米波信道的详细模拟。在文章的最后，一个全面的参考书目将帮助感兴趣的读者更深入地挖掘。
Propagation models constitute a fundamental building block of wireless communications research. Before we build and operate real systems, we must understand the science of radio propagation, and develop channel models that both reflect the important propagation processes and allow a fair comparison of different systems. In the past five decades, wireless systems have gone through five generations, from supporting voice applications to enhanced mobile broadband. To meet the ever increasing data rate demands of wireless systems, frequency bands covering a wide range from 800 MHz to 100 GHz have been allocated for use. The standardization of these systems started in the early/mid 1980s in Europe by the European Telecommunications Standards Institute with the advent of Global System for Mobile Communications. This motivated the development of the first standardized propagation model by the European Cooperation in Science and Technology (COST) 207 working group. These standardization activities were continued and expanded for the third, fourth, and fifth generations of COST, as well as by the Third Generation Partnership Project, and the International Telecommnunication Union. This paper presents a historical overview of the standardized propagation models covering first to fifth-generation systems. In particular, we discuss the evolution and standardization of pathloss models, as well as large and small-scale fading parameters for single antenna and multiple antenna systems. Furthermore, we present insights into the progress of deterministic modelling across the five generations of systems, as well as discuss more advanced modelling components needed for the detailed simulations of millimeter-wave channels. A comprehensive bibliography at the end of the paper will aid the interested reader to dig deeper.
