This paper studies the joint optimization problem of two-way relaybeamforming, the receiver power splitting (PS) ratio as well as the transmitpower at the sources to maximize the achievable sum-rate of a simultaneouswireless information and power transfer (SWIPT) system with a full-duplex (FD)multiple-input multiple-output (MIMO) amplify and forward (AF) relay, assumingperfect channel state information (CSI). In particular, our contribution is aniterative algorithm based on the difference of convex programming (DC) and onedimensional searching to achieve the joint solution. Simulation results areprovided to demonstrate the effectiveness of the proposed algorithm.
