Abstract(in English) | In this paper, we propose a novel downlink nullforming technique for space division multiple access (SDMA) in a multi-input multi-output (MIMO) channel where a basestation and all terminal stations have multiple antennas. In the SDMA system, simple beamforming is not efficient to achieve a good performance due to cochannel interference (CCI). Proposed method is based on nullforming and characterized by an antenna element selection at each terminal where the selected antenna pair satisfies the lowest spatial correlation condition in all combinations. The results obtained by the computer simulations show the selective diversity gain of the proposed method and its performance improvement due to joint detection at each terminal. |
