Multiple communication entities share the limited radio resource by cooperative protocols in the cooperative relaying systems, which have the high capacity. In this paper, the procoder technique is proposed to be applied in the cooperative relaying systems to much improve the frequency efficiency. First, the development of cooperative relaying communication is introduced in short and the potential capacity of the half-duplex cooperative relaying system is pointed. Then, several kinds of the existed precoder schemes have been analyzed and summarized. Finally, the example applications of precoder are also given.
