Abstract
This article presents simulation results for a realistic implementation of the downlink MIMO LTE Release 8 standard in fading environments. A 4x2 MIMO Channel configuration has been used as a basis in the simulation scenarios and various key characteristics of the MIMO channel and the LTE radio interface, including physical layer and radio resource management functions ware simulated and their impact on system performance is evaluated in both local and wide area scenarios. The results suggest that in practice multiuser LTE is able to support multi stream transmission with very high data rates, even for small hand held terminals. Moreover, the improvements of 4x2 MIMO transmissions for different system configurations are clearly shown over different MIMO channel environments. In depth analysis of the individual system characteristics indicates that these performance differences are due to rather uniform contributions from a set of distinctive features.
