摘要
针对非频率选择性Rice衰落MIMO移动信道的特点,提出一个MIMO衰落信道的几何模型,并据此推导出空时联合相关函数.理论分析和仿真结果表明,新的空时相关函数能准确地反映天线间距等因素对MIMO信道各链路间存在的相关性的影响,且形式更简洁.
In this paper, a modified space-time correlation model for MIMO fading channel is presented. A joint space-time correlation function for mobile frequency nonselective Rice fading channels is derived from this model. Both theoretical analysis and simulation results indicate that the new space-time correlation function is compact and can show the effects of antenna distance on correlations in MIMO channels.
