Secure Beamforming in Full-Duplex SWIPT Systems
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...
متن کاملMultiple Antennas and Beamforming for SWIPT Systems
In conventional communication systems, the use of radio frequency (RF) signals is mainly constrained on information transfer. However, RF signals also contain energy and this fact leads to the emergence of various new research areas, like RF-enabled wireless power transfer (WPT) where wireless receivers could harvest energy from RF signals radiated by an energy transmitter. There is another tec...
متن کاملA Fully Digital, Energy-Efficient, Adaptive Power-Supply Regulator
A voltage scaling technique for energy-efficient operation requires an adaptive power-supply regulator to significantly reduce dynamic power consumption in synchronous digital circuits. A digitally controlled power converter that dynamically tracks circuit performance with a ring oscillator and regulates the supply voltage to the minimum required to operate at a desired frequency is presented. ...
متن کاملDigital ultrasound: from beamforming to PACS
September 1999 7 medicamundi Digital electronics is certainly a technology that has had an enormous impact on our modern way of life. This is demonstrated every day in many instruments that we use. For instance, it is obviously reflected in what gives us dependable and accurate time measurement (digital clocks), undistorted music (compact disc), control of car engine power (electronic fuel inje...
متن کاملEnergy-Efficient SWIPT in IoT Distributed Antenna Systems
The rapid growth of Internet of Things (IoT) dramatically increases power consumption of wireless devices. Simultaneous wireless information and power transfer (SWIPT) is a promising solution for sustainable operation of IoT devices. In this paper, we study energy efficiency (EE) in SWIPT-based distributed antenna system (DAS), where power splitting (PS) is applied at IoT devices to coordinate ...
