Abstract
In this paper, we investigate the statistical characteristics of the three dimensional (3D) multiple- input multiple-output (MIMO) channels and their dependency on the dynamic range in channel impulse responses (CIRs). Our study is based on empirical results obtained from the 3D MIMO channel measurement campaigns at 6 GHz in a typical urban macrocell outdoor-to-indoor scenario. The space-alternating generalized expectation-maximization (SAGE) algorithm is employed to estimate parameters of multipath components from the measured data. The measured data is divided into groups based on the dynamic range in the measured CIRs. The second-order statistics in time and spatial domains are calculated for each group. It is found that the channel statistics shows strong dependency on the dynamic range in the measured CIRs.
本文研究了三维(3D)多输入多输出(MIMO)信道的统计特性及其与信道脉冲响应(CIRs)动态范围的关系。我们的研究基于典型城市宏蜂窝室内外场景下6 GHz 3D MIMO信道测量活动的实证结果。采用空间交替广义期望最大化(SAGE)算法从实测数据中估计多径分量的参数。根据所测红外光谱的动态范围对测量数据进行分组。计算每组的时间和空间二阶统计量。结果表明，通道统计量对所测CIRs的动态范围有很强的依赖性。
