摘要
根据目前国际上对超宽带无线通信在信道方面的研究,选取几种信道模型,从信道的特征参数出发,分析了他们各自的优缺点。根据IEEE提供的参考数据,选择了修正的S-V信道模型作为系统的信道仿真模型。仿真结果表明,该模型与UWB系统信道的特征参数非常接近,能很好地仿真物理信道的参数。
Based on the international research of UWB wireless communication channel model, some UWB channel models are analyzed based on channel characteristic in this paper. Based on the reference data which IEEE provide, the modified Saleh - Valenzuela model is chosen to simulate the UWB channel model,simulation results of the model are presented. It is shown that the channel model approaches well to the measured results of UWB channel and it can be used to simulate the parameters of the physical layer.
