摘要
结合MIMO的联合发送技术,通过优先确定接收端的解调方案,然后确定与解调方案和信道信息相匹配的调制方法,不仅实现了MIMO系统容量和性能上的优势,而且大大的降低了接收机的计算量。首先,给出多用户MIMO下行链路模型,并引出算法介绍,然后就TD-SCDMA系统应用环境进行了仿真和分析,结果说明多用户JTMIMO方案的优越性和良好的应用前景。
This paper researches joint transmission scheme combined multi-user MIMO system, in which the receiver algorithms are a priori chosen, whereas the algorithms to be used at transmitter have to be a posteriori adapted under consideration of channel state information and the receiver algorithms. Firstly, a model of multi-user MIMO downlink is introduced, We get a data transmission algorithm which can greatly reduce receiver＇s calculative cost for multi-user MIMO downlink. Then through simulation and analysis in the TD-SCDMA system, Multi-user JT MIMO demonstrates its superiority and application prosperity.
