【摘要】：針對(duì)城市移動(dòng)通信環(huán)境,提出了散射體各向異性分布的VMF分布模型.在室外宏小區(qū)的移動(dòng)通信環(huán)境下引入散射體群的概念,并結(jié)合MIMO多天線Y型陣列(UYA)和圓形陣列(UCA)拓?fù)浣Y(jié)構(gòu),使得模型能夠估計(jì)多徑衰落信道的重要信道參數(shù),如UYA和UCA的空間衰落相關(guān)函數(shù)(SFC)、衰落信道模型的信道容量及多天線陣列UYA和UCA對(duì)平均余緯的敏感度等,并延伸了SFC在求解信道協(xié)方差矩陣的應(yīng)用.結(jié)果表明:M IM O多天線系統(tǒng)的性能不僅取決于天線陣列陣元間距,還與到達(dá)角度有關(guān);所提模型的信道參數(shù)估計(jì)結(jié)果適用于實(shí)際的城市移動(dòng)通信環(huán)境.針對(duì)UYA和UCA的SFC和信道容量研究,拓展了VM F分布模型在三維空間域移動(dòng)通信領(lǐng)域的應(yīng)用,對(duì)MIMO多天線陣列的信道參數(shù)評(píng)估和無(wú)線通信系統(tǒng)仿真提供了有力的工具.
[Abstract]:The VMF distribution model of anisotropic distribution of scatterers is proposed for urban mobile communication environment. The concept of scatterer group is introduced in the mobile communication environment of outdoor macro cell. Combined with MIMO multi-antenna Y-shaped array (UYA) and circular array (UCA) topology, the model can estimate the important channel parameters of multipath fading channel. For example, the spatial fading correlation function of UYA and UCA, the channel capacity of fading channel model and the sensitivity of multi-antenna array UYA and UCA to average residual latitude, etc. The application of SFC to the solution of channel covariance matrix is extended. The results show that the performance of the multi-antenna system depends not only on the antenna array element spacing, but also on the arrival angle. The channel parameter estimation results of the proposed model are applicable to the actual urban mobile communication environment. The SFC and channel capacity of UYA and UCA are studied. The application of VM-F distribution model in 3D mobile communication is extended to provide a powerful tool for the channel parameter evaluation of MIMO multi-antenna array and the simulation of wireless communication system.
