摘要:In order to meet the requirement of channel state information in MU-MIMO downlink precoding, we propose a channel estimation scheme called TDMA-MMSE based on single user channel estimation. The performance of this scheme is analyzed. Theoretical analysis and simulation results show that this novel estimation scheme outperforms single user channel estimation. The throughout and BER performance of multi-user MIMO system with estimate channel information is close to the system with perfect channel information at high uplink SNR. Through the theoretical analysis and simulation, it shows that the proposed scheme is practicable.
