| 摘 要： | 在IEEE802.15.3a超宽带(UWB)信道模型的基础上,利用平行波近似理论,根据天线阵列的结构和多径的传播方向,提出了一种新的多入多出(MIMO)超宽带统计信道模型。各个子信道的多径幅度、相位和波达时间被引入了信道模型。子信道的信道特征参数满足超宽带信道的特征。实际测量的统计结果表明,波离角(AOD)和波达角(AOA)服从拉普拉斯分布。空间相关性、信道容量和天线间距、角度扩展之间的关系表明,该信道模型满足实际的空间相关统计特性。该模型对MIMOUWB系统的研究具有重要意义。

| Abstract: | According to the structure of antenna arrays and the propagation direction of multipath components,a new multiple input multiple output(MIMO) ultra wideband(UWB) stochastic channel model was proposed from IEEE802.15.3a standard channel model based on parallel ray approximation.The multipath amplitude,phase and arrival time were introduced into the channel model.The extracted channel parameters meet the requirement of UWB channels.From the measurement results,the angle of departure(AOD) and angle of arrival(AOA) can be approximated by Laplace distribution.The relationship between spatial correlation,channel capacity and antenna spacing,angle spread demonstrates that the channel model meets the spatial correlation characteristics in the practical environments.This channel model has great significance for the research of MIMO UWB systems. |
