Abstract :
We derive methods for linearly constrained minimum variance (LCMV) beamforming in low-rank interference. A closed-form expression for all optimal beamformers is derived and minimum-norm and projection beamformers are proposed. In addition to constructing optimal beamformers for a given interference model, we also investigate beamformer optimality under different interference scenarios.
