摘　　要：针对多用户多输入多输出系统,讨论了一种多用户下行链路使用广义空间调制传输多用户信号的方案。该方案利用广义空间调制(Generalized Spatial Modulation,GSM)技术,发送端和接收端均不需要知道信道状态信息,系统结构比较简单。同时,能有效消除信道间干扰,获得较优的系统性能。仿真分析表明,该方案在克服传统多用户MIMO系统缺点的同时,能获得较低的系统误码率。In multi-user MIMO system, a scheme that the multi-user downlink using generalized spatial modulation technique is studied. The scheme exploits the generalized spatial modulation technology, the sender and the receiver do not need to know the channel state information and the structure of the system is relatively simple. The interference between channels can be effectively eliminated and better performance of the system can be obtained. Simulation results show that the scheme in multi-user MIMO system can overcome the traditional shortcomings, at the same time, can obtain lower bit error rate.
