Abstract

This paper represents recent research on Long Term Evolution-Advanced (LTE-A) technology which is a mobile communication system supported by Multiple-Input Multiple-Output (MIMO) antenna transmission based on Downlink transmission, whereby User Equipments (UEs) are scheduled for packet transmission via information such as channel quality indicator reports, rank indication and precoding matrices. The main focus of this research is on the feedback technique via channel quality information (CQI) in order to optimize the performance of Multi-User-MIMO (MU-MIMO) transmissions in both the ideal and the measured transmission channels, using a simulation application to compare the capacity of MU-MIMO performance and Single User (SU)-MISO. The simulation shows the advantage of MU-MIMO technology in terms of optimization of the capacity of MU-MIMO performance due to feedback. This is that the best-companion PMI can be helpful with MU-MIMO precoding. The advantage of the Zero Forced Precoder technique via the feedback is that there is no interference from the other user at the receivers.

考虑信道质量信息的MU-MIMO容量优化

LTE-A技术是一种基于下行传输的多输入多输出(MIMO)天线传输支持的移动通信系统，通过信道质量指标报告、等级指示和预编码矩阵等信息调度用户设备进行分组传输。本研究的主要重点是通过信道质量信息(CQI)反馈技术来优化多用户mimo (MU-MIMO)在理想信道和实测信道中的传输性能，并利用仿真应用程序比较了MU-MIMO性能和单用户(SU)-MISO的容量。仿真结果表明，基于反馈的MU-MIMO技术在优化MU-MIMO性能方面具有优势。这就是最佳伴侣PMI可以帮助MU-MIMO预编码。通过反馈的零强制预编码器技术的优点是在接收器上没有来自其他用户的干扰。
