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