A linear radio frequency (RF) harvesting model is commonly assumed in recent simultaneous wireless information and power transfer (SWIPT) research, i.e., RF harvested power is assumed a scaled version of the input (received) power. However, rectifiers typically used in the microwave and radio frequency identification (RFID) industry are non-linear devices; thus, RF harvesting efficiency is not ...

In this paper, the secrecy performance of the two-user simultaneous wireless information and power transfer (SWIPT) sensor networks is studied and a novel secure transmission scheme of cooperative zero-forcing (ZF) jamming is proposed. The two sensors opportunistically conduct the SWIPT and cooperative ZF jamming, respectively, where the energy required for jamming the eavesdropper is provided ...

This letter solves the energy efficiency optimization problem for simultaneous wireless information and power transfer (SWIPT) systems with non-orthogonal multiple access (NOMA), input single output (MISO) power-splitting structures, where each user may have different individual quality of service (QoS) requirements about energy. Nonlinear harvesting model is used. Alternate approach adopted to...

Communication between the primary and secondary sides is pivotal to wireless power transfer (WPT) system. The system control commands feedback information need simultaneous (SWIPT). In this paper, a FSK-based SWIPT with full-duplex communication via shared channel provided. Considering complexity of coupling relationship in kind system, paper proposes an analysis method based on transmission ch...

This letter investigates the artificial noise aided beamforming design for secure simultaneous wireless information and power transfer (SWIPT) in a two-tier downlink heterogeneous network, where one femtocell is overlaid with one macrocell in co-channel deployment. Each energy receiver (ER) in femtocell can be considered as a potential eavesdropper for messages intended for information receiver...

Integrating the wireless power transfer (WPT) technology into communication system has been important for operational cost saving and power-hungry problem solving of electronic devices. In this paper, we propose a resonant beam simultaneous information (RB-SWIPT) system, which utilizes gain medium two retro-reflecting surfaces to enhance retro-reflect energy, allows devices recharge their batte...

Integrating unmanned aerial vehicles with RIS (UAV–RIS) can offer ubiquitous deployment services in communication-disabled areas, but is limited by the on-board energy of UAVs. In this paper, a novel harvesting (EH) scheme on top UAV–RIS system, called EH-RIS scheme, developed for next generation high performance wireless system. The proposed extends simultaneous information and power transfer ...

In this paper, we consider the precoding design and power allocation problem for multi-user multiple-input multiple-output (MU-MIMO) wireless ad hoc networks. In the first timeslot, the source node (SN) transmits energy and information to a relay node (RN) simultaneously within the simultaneous wireless information and power transfer (SWIPT) framework. Then, in the second timeslot, based on the...
