摘要/Abstract

摘要： 为研究分布式星群构建的虚拟MIMO的相关信道容量,建立了相关信道下的MIMO信道容量模型,提出从相关矩阵特征值分解和建立指数参数模型两方面分别分析虚拟MIMO在相关信道下的信道容量,仿真结果表明,在相关信道下,分布式星群构建的虚拟MIMO系统能够提升信道容量,但在相关信道下的信道容量会随信道相关性的增强而减弱。

Abstract: In order to study the correlated channel capacity of virtual MIMO system constructed by multi-antenna of disputed satellites,a MIMO capacity model under correlated fading channel was proposed.We analyzed the correlated fading channel capacity of virtual MIMO by decomposing eigenvalue of correlated matrix and modeling correlative coefficient using exponent model.The simulation shows that the virtual MIMO constructed by disputed satellites can promote capacity of the channel while the correlated channel capacity will recede with enhancing the channel correlation.

Key words: Disputed satellites cluster,Virtual MIMO,Channel capacity,Correlation
