摘要:

在协同中继系统中,多个用户采用相同时频资源传输信息时,采用预编码技术可以有效消除用户间干扰。本文对多用户预编码技术在中继系统中的应用进行了总结,从下行与上行链路两个方面分析了不同网络拓扑结构下预编码技术的应用。

Abstract:

Precoding techniques can effectively eliminate interference among users in cooperative relaying systems,in which several users use the same time-frequency resources. In this paper,the applications of the multi-user precoding technology in relay systems are summarized,including the downlink and uplink precoding technologies. They are analyzed in different network topologies.

Key words: cooperative relaying, precoding, multi-user
