摘要：
In this paper, the performance of decode-and forward (DF) cooperative network in presence of co-channel interference (CCI) at destination is presented. In particular, a scenario with multiple relays and multiple antennas at destination is analysed by considering the best relay selection jointly with optimum combining (OC). The moment-generating function (MGF) of the signal-to-interference-plus-noise ratio (SINR) at destination is derived in order to evaluate the average bit-error rate (BER). The analytical results are validated using Monte-Carlo simulations for several situations, showing that the proposed scenario totally mitigates the CCI and obtains a diversity gain of N(K + 1) - 1, where N is the number of antennas at destination and K is the number of cooperative relays.
