Robust beamforming based on transmit power analysis for multiuser multiple-input–single-output interference channels with energy harvesting

In this study, the authors 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. Following the worst...
