Abstract

From a system point of view, the capacity and diversity are the two main characteristics afforded by the multiple-input-multiple-output (MIMO) systems. The increasing of capacity of multiple-input-multiple-output space-time system seriously relies on the richness of multipath rays which provide uncorrelated or low-correlated parallel sub-channels. The investigation of performance of indoor MIMO systems using one correlated model presented in this paper shows that the arrangements of antenna array elements as well as the indoor scattering environment influence the spatial cross correlation which in turn influences the system performance. The results of investigation provide insights on the design of indoor space-time systems.

室内MIMO系统的性能评价
从系统的角度来看,容量和分集是多输入多输出(MIMO)系统的两个主要特征。多输入多输出空时系统容量的增加严重依赖于提供不相关或低相关并行子信道的多径射线的丰富度。本文采用一种相关模型对室内MIMO系统的性能进行了研究,结果表明天线阵列单元的布置和室内散射环境会影响空间相互关系,进而影响系统的性能。研究结果为室内时空系统的设计提供了参考。
