This paper investigates the reconfigurable intelligent surface (RIS)-empowered dynamic power splitting designs for simultaneous wireless information and transfer (SWIPT) systems while adopting various practical hardware issues. Specifically, we adopt physical size of RIS placement plane to phase-align reflected signals towards desired direction. The analytical phase shift model reflecting eleme...

Reconfigurable intelligent surface (RIS) is a revolutionary technology to enhance both the spectral efficiency and energy of wireless communication systems. However, most existing contributions mainly focused on study passive RIS, which suffers from “double fading” effect. On other hand, active equipped with amplifiers, can effectively address this issue. In letter, we propose an RIS-aided simu...

This letter studies bi-directional secure information exchange in a simultaneous wireless information and power transfer (SWIPT) system enabled by a full-duplex (FD) multipleinput multiple-output (MIMO) amplify-and-forward (AF) relay. The AF relay injects artificial noise (AN) in order to confuse the eavesdropper. Specifically, we assume a zeroforcing (ZF) solution constraint to eliminate the r...

The joint design of spatial channel assignment and power allocation in Multiple Input Multiple Output (MIMO) systems capable of Simultaneous Wireless Information and Power Transfer (SWIPT) is studied. Assuming availability of channel state information at both communications ends, we maximize the harvested energy at the multi-antenna receiver, while satisfying a minimum information rate requirem...

Abstract: In this paper, we propose a new distributed energy beamforming and information transfer (DEBIT) scheme for realizing simultaneous wireless information and power transfer (SWIPT) in multiway relay networks (MWRNs), where multiple singleantenna users exchange information via an energy-constrained single-antenna relay node. We investigate the optimal transceiver designs to maximize the a...

Nonorthogonal multiple access (NOMA) and unmanned aerial vehicle (UAV) are two promising technologies for the wireless fifth generation (5G) networks beyond. On one hand, UAVs can be deployed as flying base stations to build line-of-sight (LoS) communication links ground users (GUs) improve performance of conventional terrestrial cellular networks. other NOMA enables share an orthogonal resourc...

System splitting problem (SS problem) is to determine proper splitting points (or called splitting strategies) to split the entire interconnected transmission network into islands ensuring generation/load balance and satisfaction of transmission capacity constraints when islanding operation of system is unavoidable. For a large-scale power system, its SS problem is very complicated in general b...

Abstract Due to the excellent broadcasting characteristics of radio signals, simultaneous wireless information and power transfer (SWIPT) can transmit both energy, provide users with stable supply. Wireless channel has openness, which will lead leakage in SWIPT system. It is one research hotspots industry ensure secure transmission system where there are differences energy information.
