| 摘 要： | 针对频率选择性衰落MIMO移动信道,建立三维(3D)纯随机模型,并推导出3D MIMO信道模型的联合空时频相关函数。新的3D模型统一了现有的多种信道模型,新的联合空时相关函数综合考虑了信道收发两端的多普勒扩展、信号到达方向与离开方向的3D非均匀扩展与两端天线阵的配置。最后基于新的相关函数,分析了非均匀角度扩展参数以及阵元配置参数的变化对MIMO信道相关特性的影响。

| Abstract: | A 3D statistical channels model for mobile frequency selective fading MIMO channels was proposed and a new joint space-time-frequency correlation function was derived.The 3D channels model integrates many known channel models and the new space-time-frequency correlation function takes into account such parameters of MIMO system as the Doppler spread,the 3D angle spread,and antenna array configuration.Furthermore,the impact of nonuniform angle spread and antenna array configuration on the Cross-correlation Performance of channels were analyzed based on the new correlation function. |

| Keywords: | MIMO channel 3-D model space-time-frequency correlation function |
