摘要：Cooperative Communication is a scheme that combines the benefits of MIMO systems with relaytechniques and forms a virtual distributed MIMO system. The relaying techniques used in this paper are Amplify andForward and Decode and Forward. The performance of Amplify and Forward protocol is analysed using single relayand two relays and compared to direct link. The QPSK modulation technique is used and signals are combined usingmaximum ratio combining at receiver. The performance of Decode and Forward protocol is also analysed using anumber of relays. The signal is decoded and re-encoded at one relay and how the signal is transmitted when error occurand when error does not occur has been shown and its comparison to direct link has been done.
