This paper considers the performance of wireless power transfer (WPT) with distributed transmit beamforming (DTB) in a narrowband setting. One or more receive nodes, each equipped with energy harvesting and storage capabilities, provide periodic channel state feedback to a cluster of transmit nodes, each with an independent local oscillator, to facilitate beamforming and passband signal alignment...
This paper studies the beamforming designs for simultaneous wireless information and power transfer systems in two-way relaying (TWR) channels. The system consists of two energy-constrained source nodes which employ the power splitting (PS) to receive the information and the energy simultaneously from the power-supply relay. To maximize the weighted sum energy subject to the constraints of the quality...
