| 摘 要： | 本文提出了一种多用户MIMO-OFDM的联合发送(JT)方案,给出了系统模型,并推导出了数据发送及检测算法。此方案可以大大降低移动终端的数据检测复杂度。通过在TD-SCDMA系统应用环境中的仿真和分析,表明多用户MIMO-OFDM的JT技术具有比多用户MIMO的JT技术更优越的误码率性能。

| Abstract: | A scheme of joint transmission(JT) based on multi-user MIMO-OFDM is proposed in this paper.The system model is given,and the algorithms for the data transmission and detection are derived.The receiver's calculation cost for multi-user MIMO-OFDM downlink is reduced significantly with this scheme.The results of simulation and analysis in the TDSCDMA system are presented,which indicate the BER of the JT technique based on multi-user MIMO-OFDM is lower than that of JT technique based on multi-user MIMO. |
