We propose techniques for optimizing transmit beamforming in a full-duplex multiple-input-multiple-output wireless-powered communication system, which consists of two phases. In the first phase, the wireless-powered mobile station (MS) harvests energy using signals from the base station (BS), whereas in the second phase, both MS and BS communicate to each other in a full-duplex mode. When complete...
In this paper, we consider simultaneous wireless information and power transfer in a full-duplex (FD) communication system consisting of one FD access point A (FD-A) and one FD device B (FD-B), each being equipped with a pair of transmitter-receiver antennas for signal transmission and reception respectively. The power splitting (PS) scheme is adopted at FD-B to receive information and energy concurrently...
In this paper, we focus on the problem of optimal precoding for simultaneous wireless information and power transfer (SWIPT) in a two-hop decode-and-forward (DF) multiple-input multiple-output (MIMO) relay network, which consists of a source, a relay station, an information decoding (ID) receiver and an energy harvesting (EH) receiver. Each node in this relay network is assumed to employ multiple...
We develop a novel approach to optimal broadcast scheduling for an energy-harvesting powered transmitter with a finite-capacity battery and non-ideal circuit power consumption. Relying on the convex optimization tools, the proposed novel approach provides a low-complexity algorithm to obtain the optimal transmission policies that maximize the weighted sum-throughput for multi-input multi-output (MIMO)...
