In this paper, we study information-theoretic limits for simultaneous wireless information and power transfer (SWIPT) systems employing a practical nonlinear radio frequency (RF) energy harvesting (EH) receiver. In particular, we consider a three-node system with one transmitter that broadcasts a common signal to separated information decoding (ID) and EH receivers. Owing to the nonlinearity of...

This paper proposes a novel network framework of intelligent reflecting surface (IRS)-assisted simultaneous wireless information and power transfer (SWIPT) non-orthogonal multiple access (NOMA) networks, where IRS is used to enhance the NOMA performance (WPT) efficiency SWIPT. We formulate problem minimizing base station (BS) transmit by jointly optimizing successive interference cancellation (...

Recently, the simultaneous wireless information and power transfer (SWIPT) technique has been regarded as a promising approach to enhance performance of wireless sensor networks with limited energy supply. However, from a green communication perspective, energy efficiency optimization for SWIPT system design has not been investigated in Wireless Rechargeable Sensor Networks (WRSNs). In this pap...

We investigate the secrecy performance and energy-efficiency trade-offs associated to secure communication between a full-duplex (FD) power beacon (PB) an energy harvesting (EH) device, in presence of eavesdropper. Specifically, we analyze feasibility jamming strategy implemented at FD-PB under several practical constraints, such as imperfect self-interference (SI) cancellation, EH non-linearit...

To solve the power supply problem of battery-limited Internet Things devices (IoDs) and spectrum scarcity problem, simultaneous wireless information transfer (SWIPT) cognitive radio (CR) technology were integrated into (IoT) network to build a IoT (CRIoT) with SWIPT. In this network, secondary users (SUs) could adaptively switch between sensing, SWIPT, transmission improve total throughput. com...

Security is a critical issue in full duplex (FD) communication systems due to the broadcast nature of wireless channels. In this paper, joint design of information and artificial noise beamforming vectors is proposed for the FD simultaneous wireless information and power transferring (FD-SWIPT) systems with loopback self-interference cancellation. To guarantee high security and energy harvestin...

We studied power splitting-based simultaneous wireless information and transfer (PS-SWIPT) in multiple access channels (MACs), considering the decoding cost non-linear energy harvesting (EH) constraints at receiving nodes to study practical limitations of an EH communication system. Under these restrictions, we formulated analyzed achievable rate maximum departure regions two well-studied scena...
