Abstract(in English) | In this paper, we discuss methods of transmit-antenna selection for uplink multiuser MIMO-SDM systems. In multiuser MIMO-SDM systems, signal detection quality at a basestation is degraded by cochannel interference, and depends on the number of transmit antennas of each user. In this paper, we propose a novel method for antenna selection to increase diversity gain. The criterion of antenna selection is based on capacity using spatial filter output. Simulation results show that frame error rate performance in the multiuser MIMO-SDM systems is improved by the proposed method. In addition, we show the advantage of diversity gain to select the number of transmit antennas at each user. |
