Evaluation of the performance of indoor MIMO systems

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.
