Abstract In this survey, we will discuss about different cooperative communication schemes like Relay communication and Node cooperative system. Later on we will perform comparison between conventional communication system and cooperative relay scheme based on power efficiency. We will also discuss about various factors that will impact the efficiency of cooperative systems. We will conclude with applications of cooperative communication in LTE advanced. Cooperative communication Technological convergence in telecommunications and networking has made it possible to bring voice, data (internet) and other multimedia services over single channel. This has led to significant increase in network resource demands especially for wireless networks. To address these tremendous network demands we need to use communication resources efficiently i.e., through Cooperative communications. Cooperative communication system uses intelligent nodes or base stations that can consciously help other nodes to transfer information from the source to the final destination with increased spectral efficiency and extended coverage in case of Cellular Base stations. Cooperation in the communication networks can be realized using Relaying and Node Cooperative systems [1]. Relay communication system In Relay system, first transmitter sends the data to the relay node and information received by the relay node is forwarded to next node and finally to the destination receiver by following cooperation
