Abstract

This research proposes the design of downlink multiple-input-single-output (MISO) non-orthogonal multiple access (NOMA) simultaneous wireless information and power transfer (SWIPT) systems with time slots. This system is proposed to help the device with the lowest harvested energy by dividing the transmit time into time slots and producing the beamforming of each time slot to lift the energy level of the lowest energy device under minimum achievable rate constraints. The results show that the proposed system with time slots offers higher harvested energy than that without time slots and show that power allocation, the amount of transmit power, and the number of time slots affect system performance.
