| 摘 要： | 提出一种采用波束调度策略的MIMO与智能天线融合设计方案,用以解决MIMO传输中空域相关性问题。融合方案在天线结构上以智能天线单元组建MIMO阵列,智能天线单元之间协同工作。分析了采用波束调度时的MIMO矩阵构成及其合并接收方式,给出一种波束间空域相关性的计算方法。仿真结果表明,在小角度扩展条件下,同指向的波束相关性与全向阵元相关性相似,而波束调度策略具有良好的去相关性,能有效提高MIMO信道容量。

| Abstract: | A structure of MIMO system incorporated with smart antennas is proposed to reduce spatial correlation.The MIMO antenna arrays are constructed with several smart antenna units in accord work.The changes of the MIMO channels are analyzed,the spatial correlation between the beams is deduced and analyzed with a new method.Simulation result shows that the spatial correlation between smart antenna beams is almost the same as that the between full antennas when the beams point to the same direction.And the propose... |
