超宽带室内LOS环境信道模型研究

摘要

分析了室内LOS环境下信号传播规律,多径分量成簇到达。针对该特定环境,在S-V模型的基础上,提出将模型中簇的个数定义为2个,并对其进行了仿真。仿真结果表明,该模型与IEEE802.15.3 a信道模型相比,能较好地反应UWB室内LOS环境信道的特征参数。在其他参数不变的情况下,能减少平均超量延时和均方根时延扩展,对提高系统的数据传输速率有帮助。%The paper analyzes the rule of signal propagation in indoor LOS environment,which is that multipath components arrive in cluster.For this specific environment,the paper,based on S-V model,proposes that the number of clusters in the model should be defined
