This paper investigates beamforming design of joint transceiver in full-duplex wireless powered communication networks for throughput maximization, where a multi-antenna hybrid access point (H-AP) broadcasts wireless energy to two distributed dual- antenna users and the users cooperatively transmit information signals via their individually harvested energy. Furthermore, the users can recycle self- energy from their own transmitted signals. H-AP acts as a transceiver to transmit energy and receive information simultaneously and amplified-and-forward relaying channel is applied from users to the H-AP. In this system, we aim to maximize the throughput by jointly optimizing the energy and information beamforming vector of H-AP. As the problem is non- convex, we first apply zero forcing method to cancel the self-interference at H-AP and then employ a series of efficient variable substitutions and a low-complexity algorithm to obtain the global optimum. Simulation results demonstrate that the proposed scheme can effectively improve the achievable throughput in the WPCN.
