Simulation and analysis of UWB indoor modified S-V channel model

信道模型是无线通信系统研究和设计的基础。介绍了超宽带室内无线通信信道模型,给出了泊松过程模型、-K模型、S-V模型以及IEEE802.15.3a模型等典型UWB信道模型的建模方法和特征,针对室内信道多径分量的成簇到达特性提出了修正的S-V信道模型并对其进行仿真。仿真结果表明,该模型能较好的反应UWB信道的特征参数。

Channel models are fundamental to the study and design of communication systems. A survey on indoor wireless channels for UWB radio is given, and UWB channel models are introduced, including the poisson model, the A-K model, the S-V model, and the IEEE802.15.3a model. Modeling method and characterization of these models are coverd. Finally, in allusion to indoor channel multipath arriving in clusters, the modified S-V model is described and used to simulate the UWB channel model. Simulation results of the model show that the channel model approaches well to the measured result of UWB channel.
