摘要
通过对超宽带信号传播特性和信道特点研究,建立了非视距环境下相对精确信道模型。分析了超宽带信号室内传播规律,在仿真分析NLOS信道模型的基础上,发现其不能较好地体现出信道典型特点,因此对NLOS信道模型进行修正。仿真结果表明,修正后NLOS信道模型能更好地拟合实测数据,并能更好地体现信道特点和多径分量成簇到达特性。
A relatively accurate channel model of UWB signal channel in the non line-of-sight environment is built. The indoor UWB signal transmission pattern is analyzed, and the simulation analysis of NLOS channels model shows that it fails to reflect the typical channel characteristics, thus the need to modify the NLOS channel model. The simulation results show that the revised NLOS channels model can better fit the measured data, and can better reflect the characteristics of channel and multipath component clusters arriving feature.
