In the cellular environment, there will be channel reuse and therefore co-channel interference from other cellsexists and as a result the performance will be degraded. So it is necessary to reject the co-channel interference. In thispaper, co-channel interference (CCI) cancellation scheme for cooperative communication systems in wirelesscommunication network has been proposed. In the multipath environment, CCI causes more performance degradation inwireless network. Several interference signal mitigation methods have been proposed including Maximum Likelihood(ML), Zero Forcing (ZF), MMSE and Successive Interference Cancellation (SIC). Of all these techniques, MMSE SICwith optimal ordering will reject CCI efficiently and offers performance improvement compared with conventional SIC.In this paper, the overall system performance has been demonstrated in terms of bit error rate (BER) by consideringRayleigh fading channel.
