Abstract:

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.

Key words: cooperative system, precoding, virtual antenna array, topology
