Robust beamforming design for multiple-input–single-output secrecy multicasting systems with simultaneous wireless information and power transmission

In this study, the authors study simultaneous wireless information and power transfer for multiuser multiple-input–single-output secure multicasting channels with imperfect channel state information. First, a robust secure beamforming design is considered, where the transmit power is minimised subje...
