| 摘 要： | 在几何单反射椭圆信道模型和几何随机信道模型基础上,针对电磁波传播过程中出现的多反射特性,提出一种多反射特性的无线信道建模方法。把该方法应用于超宽带信道研究,可以得到UWB信道的几何随机多反射模型(GSMB)。使用该方法对两个UWB信号传播环境进行仿真分析,仿真得到的UWB信道功率延迟分布与实验结果基本一致,同时也验证了其他研究者关于UWB信道中的成簇现象具有确定性的结论。

| Abstract: | Aiming at the multiple bounces characteristics of electromagnetic wave,a modeling method for wireless channels with multiple bounces is proposed based on geometrically-based single bounce ellipses model(GBSBEM) and geometry-based stochastic channel model(GSCM),through which geometrically-based stochastic multiple bounces(GSMB) model for ultra-wideband(UWB) channel is obtained.The UWB channel characteristics of two indoor environments are simulated.The simulation results demonstrate that the power delay profiles(PDPs) are similar to the ones from other experiments,and there are deterministic factors in clustering phenomena of the UWB channel,which corresponds well with the conclusions of other researchers. |
