摘要:

针对非频率选择性瑞利衰落信道,在三维(3D,three-dimensional)空间域信道模型中分析和研究紧凑型双环阵列(DUCA,double uniform circular array)多天线MIMO系统。采用互耦效应的等效电路模型,首次导出DUCA天线阵元间的信号衰落相关性的通用表达式,阐明互耦效应的影响机理。分析结果与传统MIMO线性阵列(ULA,uniform linear array)和单环阵列(UCA,uniform circular array)相比较,阵元空间配置及其互耦效应将对信号衰落相关性起到决定性作用。研究结果对未来massive MIMO多天线的设计和性能优化具有很好的指导意义。

Abstract:

A MIMO multi-antenna system of compact double uniform circular array (DUCA) in three dimensional direc-tional frequency non-selective Rayleigh fading channel was analyzed and investigated. Equivalent network model of MIMO multi-antenna array considering MC effect was established, general expressions of correlations were derived and the relationship between correlations with and without MC was classfied. Then, the results were compared with general uniform linear array (ULA) and uniform circular array (UCA). It was concluded that the deployment of antennas plays a decisive role in correlations between antennas. The research has a good sense on designation of spatial massive MIMO multi-antenna array and system optimization.

Key words: multiple input multiple output antenna array, double uniform circular array, mutual coupling effect, signalfading correlation
