In this paper, MU-MIMO transmission in LTE Uplink is implemented in a simulator and its performance is evaluated. Using the Matlab based Vienna LTE uplink simulator, new features are added to the system to be able to evaluate and discuss the capabilities of the multi user transmission in a LTE mobile communication network. After the basic MU-MIMO functions, a Round Robin scheduler and a zero forcing filter in the receiver, some extra implementations are carried out to make a more complete simulator able to make a wide range of different simulations. A new scheduler, based on a greedy multi-user implementation, the possibility of including channel estimation errors, and two new receivers based on a minimum mean square error (MMSE) filter and a successive interference cancellation (SIC) filter based on MMSE are implemented and several simulations about are carried out.
