摘要: 该文研究降低多用户MIMO下行链路检测复杂性的联合发送技术。首先给出了多用户MIMO下行链路模型，在此基础上导出了数据检测算法，每个移动台只需一个线性滤波器来完成数据检测，大大地降低了接收机的计算量，然后就TD-SCDMA系统应用环境进行了仿真和分析，结果说明了多用户MIMO联合发送方案的优越性和良好的应用前景。Abstract: This paper researches low complexity detection scheme based on joint transmission scheme in multi-user MIMO downlink. Firstly, a model of multi-user MIMO downlink is introduced. A data transmission algorithm is got which can greatly reduce receivers calculative cost for multi-user MIMO downlink. And each mobile station receiver needs only one linear filter. Then through simulation and analysis in the TD-SCDMA system, Multi-user JT MIMO demonstrates its superiority and application prosperity.
