荷叶状空间信道模型与MIMO多天线系统分析
Lotus leaf geometric channel modeling and MIMO multi-antenna system performance
摘要
Abstract
A multiple input multiple output (MIMO) antenna system with the uniform linear array (ULA) and uniform circular array (UCA) in three dimensional suburb mobile communication environment is analyzed and investigated.The lotus leaf geometric channel model is proposed,and the probability density function of arriving waves is calculated.Then,expressions for signal correlations are derived in two ways, namely,from steering vectors of antenna arrays and autocorrelation functions of the fading channel,and the relationship between correlation with the spacing of antenna arrays and angular parameters is classified.The results are compared with those in actual channel environment,and it is shown that the channel capacity of the lotus leaf geometric channel model is in agreement with that of the latter. It is concluded that the deployment of antenna array spacing plays a decisive role in correlations between angular spreads of multipath signals.关键词
