基于测试数据的室内超宽带信道建模研究

摘要

Based on indoor UWB measurements, cluster-based tapped-delay-line (CDL) models and novel path-loss models with respect to the transceiver distance and frequency band were developed in the paper. The new path loss models as the function of both the distance and frequency were derived. Meanwhile, the amplitudes of from line-of-sight signal and non-line-of-sight signal met the distribution of Ricean and Rayleigh. The models have great guiding significance for the simulation and design of UWB wireless system.%基于室内超宽带信道测量研究建立了基于簇的时延抽头模型以及与距离和载频有关的新颖的路径损耗模型,建立了路径损耗同时与距离和频率的依赖关系.同时,研究发现视距和非视距接收信号幅度分别满足莱斯和瑞利分布.该模型对超宽带无线系统仿真和设计有重要的指导意义.
