This paper considers power splitting (PS)-based simultaneous wireless information and power transfer (SWIPT) for multiple-input multiple-output (MIMO) interference channel networks where multiple transceiver pairs share the same frequency spectrum. As the PS model is adopted, an individual receiver splits the received signal into two parts for information decoding (ID) and energy harvesting (EH...

In this paper, we develop a tractable model for joint downlink (DL) and uplink (UL) transmission of K-tier heterogeneous cellular networks (HCNs) with simultaneous wireless information and power transfer (SWIPT) for efficient spectrum and energy utilization. In the DL, the mobile users (MUs) with power splitting receiver architecture decode information and harvest energy based on SWIPT. While i...

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...

Two vital challenges arise in the next generation 5G networks: scarcity of spectrum and the aspect of energy efficiency (EE). In this letter, we first formulate the prime issue, i.e., energy harvesting (EV) for 5G wireless networks, in which spectrum and energy resources are efficiently received and resourcefully managed. Thereafter, we introduce a medium access control (MAC) scheme for dual ti...

Power Line Communication (PLC) and Simultaneous Wireless Information Transfer (SWIPT) are popular examples of applications, where power information transmitted simultaneously. In most cases, different devices have been used to generate the communication signals independently. Usually, is superimposed onto signal using an external modulator. Recently, converters pulses not just for conversion bu...

Wireless power transfer (WPT) technology enables a cost-effective and sustainable energy supply in wireless networks. However, the broadcast nature of signals makes them non-excludable public goods, which leads to potential free-riders among receivers. In this study, we formulate provision problem as goods problem, aiming maximize social welfare system an transmitter (ET) all users (EUs), while...

In this letter, three hybrid simultaneous wireless information and power transfer (SWIPT)/ambient energy harvesting (EH) structures are analyzed for a relay node from both source the ambient environment. The EH based on an channel estimation splitting scheme (ACEPS), data transmission (ADTPS), combination (ACPS). Closed-form expressions of achievable rates derived. Numerical results demonstrate...

Wireless power transfer by magnetic induction offers a simple to use way to recharge mobile devices like e.g. mobile phone, music players or medical sensors. As shown by a previous report and an existing Power Pad demonstrator, wireless inductive power transfer is possible with a good power efficiency and low magnetic radiation only on a surface and with local activation underneath the mobile d...
