介绍了一种多用户多输入多输出（MIMO）系统下行链路的发射预处理技术。它将多用户MIMO下行信道分解为多个并行独立的单用户MIMO下行信道。一些关键特性是每个等效单用户MIMO信道具有与传统单用户MIMO信道相同的特性，并且多用户系统的发射天线的数量增加一个，每个用户的空间信道的数量增加一个。仿真结果也提供了这些结果表明，我们的技术在性能和容量方面的潜力。
We introduce a transmit preprocessing technique for the downlink of multiuser multiple-input multiple-output (MIMO) systems. It decomposes the multiuser MIMO downlink channel into multiple parallel independent single-user MIMO downlink channels. Some key properties are that each equivalent single-user MIMO channel has the same properties as a conventional single-user MIMO channel, and that increasing the number of transmit antennas of the multiuser system by one increases the number of spatial channels to each user by one. Simulation results are also provided and these results demonstrate the potential of our technique in terms of performance and capacity.
