摘要
无线信道的建模与仿真历来是宽带无线移动通信系统设计中的难点。注意到实际分析的有效性,在深刻理解相关传播机制的基础上,对空时信道模型提出了一种分层次描述的方法,与此前的相关研究工作相比,对有关问题的研究进一步趋于实际移动通信场景下的具体问题,并能为其他空时处理方法提供依据,因此,有关研究结果将有助于对相关物理现象的更好认识,并促进宽带无线移动通信场景下信道建模与仿真技术的实际应用研究。
The modeling and simulation of wireless channel have been the difficult point in the design of wideband mobile radio system. Noticing the actual analytical availability, based on thorough understanding of related transmission mechanism, a layered modeling approach is suggested in this article. Compared with the early related research, the paper is more significative in theory and factual practice, and can offer the reference for other spatial-temporal processing methods. What is more, the research will help the recognizing of related physical phenomenon, and the modeling approach presented in this paper will promote the study of system- level simulation.
