摘要
提出一种基于随机波动模型(S-V模型)的改进室内模型,即修正的泊松超宽带(Ultrawideband,UWB)室内视距(Line of sight,LOS)信道模型,即两簇模型。模型的信道冲激响应具有两个确定的簇,每个簇内具有随机到达的多径射线。模型将多径增益分为能量较强和能量较弱两部分,在UWB室内LOS环境的小尺度多径特性上比S-V模型更好地拟合了UWB室内LOS环境测量数据,从而弥补了S-V模型和IEEE 802.15.3a标准模型对室内LOS信道环境性能的不足。
This paper suggests a new model based on the S-V model. The channel impulse has two clus ters, the multipath has random arrival probability, and the model differentiates between the strong power and the infirmness power. The model can forecast the indoor LOS environment in the small channel model. So it can remedy the defective performance, of the S-V model and the IEEE 802.15.3a, of indoor LOS channel environment.
