摘要
协同系统与多入多出系统具有相似性,在协同系统中引入预编码技术是方便可行的。本文从本地和虚拟天线阵的构成方式及系统拓扑等角度出发,对协同系统中的预编码技术进行了分类整理,总结了其研究现状。
Due to the similarity between multi-input-multi-output systems and cooperative systems, precoding techniques can be easily introduced into cooperative systems. In this paper, researches on precoding techniques in cooperative systems are summarized. Based on configuration of local or virtual antenna arrays and system topology, precoding techniques in cooperative systems are divided into three categories and a few of sub-categories.
