In this paper, a multiple-input multiple-output (MIMO) two-way amplify-and-forward (AF) relay system is investigated, where simultaneous wireless information and power transfer (SWIPT) technique is applied at the massive-antenna relay node which splits the received signal into two parts, one portion is used for information decoding (ID) and the other portion is adopted for energy harvesting (EH). By considering power splitting (PS) scheme of SWIPT, the relay node consumes the harvested energy to forward the ID signal to two users. When the number of relay antennas approaches to infinity, the deterministic sum-rate of the relay system is analyzed. The close-form expression of optimal PS factor is derived. Finally, the analytical results are validated by the simulations.
