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 as two,and provides its simulation.The simulation results show that the model,as compared with the IEEE802.15.3a channel model,can better reflect the characteristic parameters of the channels in UWB indoor LOS environment.When other parameters are unchanged,the average excess delay and RMS delay spread can be reduced,which helps to improve the data transmission rate of system.
