Abstract: Based on the multiuser MIMO uplink capacity and optimal antenna selection schemes, a sub-optimal transmitting antenna selection algorithm is proposed, termed Multiuser Iterative Elimination Antenna Selection (MIEAS). Simulation results show that, when apply to the uplink of MIMO systems, MIEAS provides performance that is very close to the optimal algorithm in capacity, with considerably lowered computation complexity.
