Objectives: To study the review of Amplify and Forward bidirectional relaying with channel estimation error and cochannel interference. Methods/Statistical analysis: This research approach is based on detailed study and analysis of two way relaying network with Amplify and Forward technique. Amplify and forward technique is preferred over decode and forward technique because it is simpler than decode and forward technique as it does not include the complex procedure of encoding and decoding process. it also includes the performance of two way relaying network or we can say bidirectional network with relay selection scheme and all relay participating case under the effect of Co-Channel Interference (CCI) and Channel Estimation Error (CEE) .Comparison between one way relaying and two way relaying is also included in this paper. Findings: Wireless communication suffers from various problems like CCI and CEE. Previous research work on bidirectional relaying networks doesn’t include the effect of CC1 and CEE, but in practical, these errors exists so it is important to study the effect of these problems in our wireless communication networks. This research includes the complete survey of amplify and forward technique with one way relaying channel and two way relaying channel. It is also shown that performance of relay selection case is not always better than all relay participating case for two way relaying network. Cooperative communication is an efficient technique to deal with these types of problems by offering significant multiplexing and diversity gains without increasing power and bandwidth. Two way relaying helps to improve the overall system performance in wireless networks. Cooperative communications also deals with the various problems like fading and shadowing with the help of two way relaying. It has been proved that two way relaying is spectrally efficient technique which provides a way to surmount half duplexing loss in one way relay channel. Application/Improvements: Wireless Communication has gained a lot of interest nowadays. Our future generation requires higher data rates and a more suitable transmission with a adequate quality of service. Two Way Relaying techniques is an efficient technique to fulfill these demands with less interference.
