With the integration of Internet and multimedia applications in next generation wireless communications, the demand for wide-band high data rate communication services is growing. In recent years, multiple transmitter and receiver antennas are employed in the wireless communications systems to adapt various demands of high speed wireless links and improved signal to noise ratio. In order to take full advantage of the Multi Input Multi Output (MIMO) systems, relay selection technique is needed at the transmitter & receiver side. Many relay selection techniques exist in literature. In this paper, a brief review of previous paper which done with relay selection for MIMO system is discussed.
