中文摘要：

为了研究在各向同性散射和非各向同性散射中信道的传输特性,建立一种椭圆散射信道模型,同时在发射端和接收端设置均匀线性阵列以研究多输入多输出系统性能.假设波达信号到达角服从Von Mises分布,在定量给出到达角和发射角关系的条件下分析了参考模型的相关函数和信道容量.另外,在精确多普勒扩展法的基础上提出一种改进的参数计算方法,在参考模型的基础上得到了仿真模型,模型的数值结果阐明了Von Mises分布下信道的相关特性.理论分析和仿真结果表明,信道仿真器和参考模型有近乎一致的时间相关性,同时该模型的提出也拓展了空间统计信道模型的研究.

英文摘要：

To study the transmission characteristics of the channel under isotropic and non-isotropic scattering environments, a geometric elliptical scattering model was established.Both the transmitter and receiver are adapted uniform linear array to research multiple-input multiple-output performance.First, assume that the angle of arrival （AOA） obey Von Mises density distribution.In the quantitative analysis of the relationship between AOA and angel of departure, the time auto correlation function, the spatial correlation function of the reference model are analyzed, so as the channel capacity.In addition, a parameter calculation method based exact doppler spread was proposed, and a simulation model was obtained based on a reference model.The statistics of the proposed model illustrates the influence of the characteristic of the channel model under the Von Mises distribution.Analysis and simulation show that the channel simulator and the reference model have almost the same time correlation function, and this model also extends the research of spatial statistical channel model.
