Summary:
In this paper, we consider MIMO wireless energy transfer system in which one energy receiver harvests energy from radio frequency signal transmitted from one energy transmitter. We deal with antenna selection problem to maximize harvested power to total power consumption ratio. It is shown that the singular value of the reconstructed channel by selection determines our objective. Against high computation complexity of exhaustive search for optimal selection, we proposed greedy selection algorithm based on the norm of column associated with each antenna. Simulation results show that the proposed algorithm achieves near optimal performance.
