摘要：

The knowledge of channel state information (CSI) at the receiver or transmitter is the key factor in devising a suitable transmission technique for a Multiple Input Multiple Output (MIMO) system. This paper investigates an impact of imperfect CSI at transmitter on the performance of a downlink multiuser MIMO system. A new transmission technique is proposed to enhance the system performance under such a condition. The simulation results confirm the advantageous of the proposed technique over the other techniques presented in the MIMO literature.
