The cooperative communication becomes an important topic in the field of a wireless communication network to improve the reliability and speed of communication over long-distance and curve bed surface. As the distance is increasing between transmitter and receiver, the transmitter RF power requirement goes up to maintain the required SNR. The cooperative communication is an alternative way to fulfill this requirement with the help of relaying techniques. There is a number of research articles have been published in the area of cooperative communication. The major research works have been carried out the AF, DF and CF protocols. Future generations of cellular communications require higher data rates and a more reliable transmission link with the growth of multimedia services while keeping the satisfactory quality of service, Multiple inputs multiple output (MIMO) antenna systems have been considered as an effective approach to address these demands by offering significant multiplexing and diversity gains over single antenna systems without increasing bandwidth and power. Although MIMO systems can unfold their huge benefit in cellular base stations, they may face limitations when it comes to their deployment in mobile handsets. To overcome this drawback, relays (fixed or mobile terminals) can cooperate to improve the overall system performance in cellular networks. Cooperative communications can effectively combat the severity of fading and shadow through the assistance of relays. It has been found that using relays the capacity and coverage of cellular networks can be extended without increasing mobile transmit power or demanding extra bandwidth.
