In this paper, we investigate the problem of two-way relay beamforming optimization to maximize the achievable sumrate of a simultaneous wireless information and power transfer (SWIPT) system with a full-duplex (FD) multiple-input multipleoutput (MIMO) amplify-and-forward (AF) relay. In particular, we address the optimal joint design of the receiver power splitting (PS) ratio and the beamforming matrix at the relay node given the channel state information (CSI). Our contribution is an iterative algorithm based on difference of convex (DC) programming and one-dimensional searching to achieve the joint optimal solution. Simulation results are provided to demonstrate the effectiveness of the proposed algorithm.
