Robust Beamforming Design for SWIPT in Cellular Internet of Things

In this paper, we study a practical cellular Internet-of-Things (IoT) system enabled with simultaneous wireless information and power transfer (SWIPT), where a multiple-antenna base station (BS) deployed at the center of the cell and massive number of IoT devices access the network via the BS. Note that each IoT device has a non-linear energy harvesting (EH) receiver and carries out imperfect successive interference cancellation (SIC) during...
