3G LTE Simulations Using Measured MIMO Channels

In this article we present downlink simulation results for a realistic implementation of the LTE (Long Term Evolution) 3G standard. In contrast to previous studies, actual measured channels (as opposed to computer generated artificial channels) have been used in the simulation. The used 2 times 2 MIMO channels were measured using two realistic receiver mockups, one laptop and one handset, as well as a pair of reference dipole antennas. The results suggest that LTE is able in practice to support multi stream transmission with very high data rates, even for small hand held terminals. Also, the improvements of 2 times 2 MIMO over SISO transmission are clearly shown.
