TLDR
Simulation results show the superiority of the proposed schemes on EE, both the optimal algorithm and the low complexity sub-optimal algorithm.Abstract:
This letter studies the energy efficiency (EE) optimization problem for the simultaneous wireless information and power transfer (SWIPT) MIMO systems with statistical channel state information (CSI) feedback. Considering the further transmission of the energy harvesting node, the potential capacity produced by the transferred energy is counted in system capacity. Both the optimal algorithm and the low complexity sub-optimal algorithm are proposed. Simulation results show the superiority of the proposed schemes on EE.read more
