An Improved Interference Cancellation Scheme for Two-User MIMO-MAC


Xinji Tian and Cheng Song

Multi-Input Multi-Output (MIMO) Multiple Access Channels (MAC) for two-user suffers from co-channel interference. For this problem, an interference cancellation scheme based on limited feedback is proposed. Through diagonalization processing for transmitted signals according to feedback information, the co-channel interference is eliminated. Not only the reliability is improved, but also each signal can be Maximum Likelihood (ML) decoded separately. Simulation results show that, compared to the existing interference cancellation scheme, the gain of the proposed scheme is 2dB at the Bit Error Rate (BER) of 10-3.
