  • In this paper, a sub-optimal transmission technique is proposed for uplink MU-MIMO systems, which is called Maximum Eigenmode BeamForming (MEBF). Compared with the optimal transmission technique (i.e., Multi-User Iterative Water-Filling, MU-IWF), the complexity of MEBF is very low since each User Equipment (UE) transmits only in its maximum eigenmode direction. Theoretical analyses show that MEBF is asymptotically optimal with the number of UEs increasing. It is also shown by simulation results that for a finite number of UEs, MEBF is nearly optimal.
