摘要
基于时域射线跟踪方法对室内超宽带信号传播进行了仿真和分析。设计了一种应用于室内带金属家具非视距环境的超宽带信号信道仿真模型,用以分析和描述超宽带信号经室内反射、透射和绕射传播后的时域电场强度,同时比较分析了仿真得到的视距传播和非视距传播中的多径传播、功率时延分布等传播参数。仿真结果可以为室内复杂环境中超宽带无线通信网络覆盖与优化提供理论依据。
The indoor propagation characteristics for uhra-wideband (UWB) signal are simulated and analyzed using the method of time-domain ray tracing. An UWB signal model is developed to analyze and describe the time-domain electric field of an UWB signal propagating in an indoor non-line-of-sight (NLOS) environment with metallic furniture. Some propagation characteristics are discussed such as the multipath propagation, power delay profile and so on in terms of line-of-sight (LOS) and NLOS. These results provide the theoretical basis for wireless communication network coverage and optimization of UWB signal in indoor complex environment.
