Energy Harvesting Noncoherent Cooperative Communications
, 2015 This paper investigates simultaneous wireless information and power transfer (SWIPT) in energy harvesting (EH) relay systems. Unlike existing SWIPT schemes requiring the channel state information (CSI) for coherent information delivery, we propose a ...

SWIPT Massive MIMO Systems With Active Eavesdropping [PDF]
IEEE Journal on Selected Areas in Communications, 2019 We consider the optimization of the downlink transmission for simultaneous wireless information and power transfer (SWIPT) in multi-cell massive multiple-input multiple-output systems. The system comprises a two-antenna active energy harvester (EH) which is capable of legitimately harvesting energy via one antenna, and illegitimately and actively ...

Power Allocation and Scheduling for SWIPT Systems with Non-linear Energy Harvesting Model
, 2016 In this paper, we design a resource allocation algorithm for multiuser simultaneous wireless information and power transfer systems for a realistic non-linear energy harvesting (EH) model. In particular, the algorithm design is formulated as a non-convex

Secrecy outage of SWIPT in the presence of cooperating eavesdroppers [PDF]
AEU - International Journal of Electronics and Communications, 2017 This work investigates the secrecy performance of a simultaneous wireless information and power transfer system that operates in the presence of cooperating eavesdroppers. The multi-antenna access point’s transmission is used for information-decoding by a multi-antenna node and for energy-harvesting (EH) by multiple single-antenna nodes.
