N2 - In this paper, we study the robust transmit beamforming and receive power splitting design for simultaneous wireless information and power transfer in multiuser multiple-input single-output interference channel with imperfect channel-state information at the transmitter. We consider two types of receivers, namely Type I and Type II receivers according to the ability of eliminating the interference from received signals. Following the worst-case model, we minimize the average total transmit power subject to a set of energy harvesting constraint and SINR constraint for Type I receiver or SNR constraint for Type II receiver, respectively. Based on the Lagrangian multiplier method, we propose a lower and upper bounds algorithm that is able to achieve a global optimum for Type I receiver. For Type II receiver, we transform this problem into a relaxed semidefinite programming problem, which can be solved efficiently. It is shown from simulation results that our proposed method outperform the non-robust scheme.
