A Minimum Co-User Interference Approach for Multi-User MIMO Downlink Precoding
2006
IEEE International Conference on Acoustics Speed and Signal Processing Proceedings
This paper proposes multi-user precoding schemes for MIMO wireless networks. We design precoders that minimize the interference power caused by a user on all other users, as opposed to forcefully nulling the interference. The resulting scheme relaxes the traditional constraint on the number of transmit and receive antennas
