Receiver Antenna Partitioning for Simultaneous Wireless Information and Power Transfer
Powering mobiles using microwave power transfer (PT) avoids the inconvenience of battery recharging by cables and ensures uninterrupted mobile operation. The integration of PT and information transfer (IT) allows wireless PT to be realized by building on the existing infrastructure for IT and also leads to compact mobile designs. As a result, simultaneous wireless information and power transfer...
متن کاملTwo-Way Multi-Antenna Relaying with Simultaneous Wireless Information and Power Transfer
In this paper, we propose various kinds of two-way multi-antenna relaying with simultaneous wireless information and power transfer (SWIPT) and investigate their performance. Specifically, we first consider a two-way relay network where two single-antenna end nodes communicate with each other through a multi-antenna relay node that is energy constrained. This relay node harvests energy from the...
متن کاملPoor Application of Smart Antenna Technologies in Simultaneous Wireless Information and Power Transfer
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...

متن کاملMulti-Objective Power Allocation for Energy Efficient Wireless Information and Power Transfer Systems
Simultaneous wireless information and power transfer (SWIPT) provides a promising solution for enabling perpetual wireless networks. As energy efficiency (EE) is an important evaluation of system performance, this thesis studies energy-efficient resource allocation algorithm designs in SWIPT systems. We first investigate the trade-off between the EE for information transmission, the EE for powe...
