On the study of interference mitigation method in K-user MIMO interference channel

A study of interference mitigation methods is explained. Interference mitigation has become a major issue in current communication system. Understanding the advantages and drawbacks of each method is essential so that it could be implemented effectively. In this paper, we compare five interference mitigation methods, consists of 2 ordinary equalization methods, matched filter and zero forcing; and 3 interference alignment methods, min weighted leakage interference, alternating minimization, and max SINR. Simulation is done inK-user MIMO interference channel. Through sum rate and bit error rate performance we show that max SINR method has the best performance although the complexity is larger than an ordinary equalization.
