Eun Cheol Kim, Jae Sung Park, Jin Young Kim · 2009
In this paper, we propose co-channel interference (CCI) cancellation strategy for cooperative communication systems in wireless communication network. In the proposed strategy, CCI is mitigated by zero forcing (ZF) or minimum mean square error (MMSE) receivers. Moreover, successive interference cancellation (SIC) efficiently. And we analyzed and simulated the proposed system performance in Rayleigh fading channel. In order to justify the benefit of the proposed strategy, the overall system performance is illustrated in terms of bit error rate and compared with that of conventional interference cancellation receiver.
