This paper investigates a multiuser multiple-input single-output (MISO) full-duplex (FD) system for simultaneous wireless information and power transfer (SWIPT), in which a multi-antenna base station (BS) simultaneously sends wirelessly information and power to a set of single-antenna mobile stations (MSs) using power splitters (PSs) in the downlink and receives information in the uplink in FD ...

Simultaneous wireless information and power transfer (SWIPT) presents a genuine opportunity toward achieving sustainable low-energy devices. This paper introduces receiver design for an energy harvesting sensor node (SN). The is equipped with multiple radio frequency (RF) inputs. Furthermore, the contains separate circuitries decoding (ID) (EH) dynamic splitting (PS). ID EH circuits are connect...

Physical layer security is a key issue in the full duplex (FD) communication systems due to the broadcast nature of wireless channels. In this paper, the joint design of information and artificial noise beamforming vectors is proposed for the FD simultaneous wireless information and power transferring (FD-SWIPT) systems. To guarantee high security and energy harvesting performance of the FD-SWI...

In this paper, we consider a time-switching (TS) co-located simultaneous wireless information and power transfer (SWIPT) system consisting of multiple multi-antenna access points which serve multiple single antenna users. In this scenario, we propose a multi-objective optimization (MOO) framework to design jointly the Pareto optimal beamforming vector and the TS ratio for each receiver. The obj...

In wireless power transfer, a concept originally conceived by Nikola Tesla in the 1890s, energy is transmitted from a power source to a destination over the wireless medium. The use of wireless power transfer can avoid the costly process of planning and installing power cables in buildings and infrastructure. One of the challenges for implementing wireless power transfer is its low energy trans...

In this article, a bidirectional relaying (BR) non-orthogonal multiple access (NOMA) with simultaneous wireless information and power transfer (SWIPT) termed as BR NOMA-SWIPT is proposed investigated for the Internet of Things (IoT) relay networks. Here, NOMA users in one group can communicate or exchange another through common energy harvesting (EH) based relay. The EH exploits radio frequency...

The increasing demands of power supply and data rate for mobile devices promote the research simultaneous wireless information transfer (SWIPT). Optical SWIPT, as known light (SLIPT), has potential providing high-capacity communication high-power charging. However, SLIPT technologies based on light-emitting diodes have low efficiency due to energy dissipation over air. Laser-based need strict p...

this paper deals with scrutinizing the convergence properties of iterative methods to solve linear system of equations. recently, several types of the preconditioners have been applied for ameliorating the rate of convergence of the accelerated overrelaxation (aor) method. in this paper, we study the applicability of a general class of the preconditioned iterative methods under certain conditio...
