摘要：

摘要：在IEEE 802.11ac Draft 2.0 标准草案的基础上，针对其新引入的多用户MIMO传输机制进行了深入研究，提出了几点改进的优化设计方案，并完成了相应的性能分析。最后对IEEE 802.11ac的多用户MIMO传输方案进行了系统的性能分析，仿真结果表明，改进的传输方案在误比特率(BER)和吞吐量方面获得了明显的性能增益，且与针对性能的理论分析与仿真结果相吻合。

Abstract:

The recent IEEE 802.11ac adopted a novel multi-user access technique,which was the downlink multi-user MIMO (MU-MIMO) transmission.This was very different from the former IEEE 802.11 standard's protocols.The MU-MIMO transmission technique in IEEE 802.11ac draft was studied and proposed some optimal designs.Finally,the performance of the IEEE 802.11ac MU-MIMO transmission schemes and gives the simulations.The simulation results show that the proposal transmission schemes can achieve gains of BER and throughput in theory and simulations.
