Interference self-mitigating beamforming for the K-user MIMO IC
This work studies distributed linear transmission strategies for the multiple-input multiple-output (MIMO) interference channel with multiple concurrent links. We introduce the notion of interference self-mitigating beamforming (ISM-BF), where each transmitter minimizes the interference it causes to other users while satisfying its own signal-to-interferenceplus-noise ratio requirement. The computation of the optimal transmit beamformers is shown to decouple into a generalized eigenvector problem. In addition, we analyze the optimality and uniqueness of the proposed distributed beamforming solution. Numerical simulations of the sum rate performance of ISM-BF show it to be a viable alternative to interference alignment-based techniques.
