Considering simultaneous wireless information and power transfer (SWIPT), we study a multiple-input-single-output (MISO) secrecy channel which consists of a multi-antenna transmitter and a cooperative jammer (CJ), multiple multi-antenna energy receivers (ERs), i.e., potential eavesdroppers, and multiple single-antenna co-located receivers (CRs). Both transmitter and CJ send the intend signal with artificial noise (AN) and jamming signal to interfere with the ERs. All receivers (CRs and ERs) adopt a power splitter to decode information and harvest power simultaneously. We exploit AN and CJ to facilitate efficient wireless energy transfer and secure transmission. Our aim is to maximize the minimum harvested energy among all ERs and CRs subject to the total power constraints at the transmitter and CJ while guaranteeing the minimum secrecy rate for each CR above its requirement. By incorporating norm-bounded channel uncertainty model, we propose a joint design of robust secure transmission. The original problem is solved by a two-step approach. In the first step, the proposed problem is reformulated as a sequence of semidefinite programs (SDPs). In the second step, the proposed problem can be handled by one-dimensional search to attain the optimal solution. Simulation results indicate that the performance of the proposed scheme outperforms that of separated AN-aided or CJ-aided scheme.

MULTI-GROUP MULTICAST BEAMFORMING FOR SIMULTANEOUS WIRELESS INFORMATION AND POWER TRANSFER
Demir, Özlem Tuğfe; Tuncer, Temel Engin (2015-09-04)
In this paper, simultaneous wireless information and power transfer (SWIPT) concept is introduced for multi group multicast beamforming. Each user has a single antenna and a power splitter which divides the radio frequency (RF) signal into two for both information decoding and energy harvesting. The aim is to minimize the total transmission power at the base station while satisfying both signal-to-interference-plus- noise-ratio (SINR) and harvested power constraints at each user. Unlike unicast and certain ...
Concurrent operation of wireless power transfer based contactless slip ring and motor drive system with a single converter
Ayaz, Enes; Keysan, Ozan; Department of Electrical and Electronics Engineering (2022-9)
This thesis presents a novel approach for concurrent power transfer to wired and wireless systems using a single inverter. This proposed approach fits a cost-effective solution to wireless power transfer (WPT) systems used in contactless slip rings (CSR) applications such as sensors, radars, or wind-turbine pitch controls. In conventional systems, there are two separate converters: one is for the motor drive, and the other is for the WPT system. It is proposed that the switching harmonics of the motor drive...
Secure Wireless Powered and Cooperative Jamming D2D Communications
Chu, Zheng; Nguyen, Huan X; Le, Tuan Anh; Karamanoglu, Mehmet; EVER, ENVER; Yazıcı, Adnan (2017-10-01)
This paper investigates a secure wireless-powered device-to-device (D2D) communication network in the presence of multiple eavesdroppers, where a hybrid base station (BS) in a cellular network not only provides power wirelessly for the D2D transmitter to guarantee power efficiency for the D2D network, but also serves as a cooperative jammer to interfere with the eavesdroppers. The cellular and D2D networks can belong to different service providers, which means that the D2D transmitter would need to pay for ...
Carrier Phase Shift Method of SPWM for Concurrent Wired and Wireless Power Transfer Systems
Ayaz, Enes; Altun, Ogün; Keysan, Ozan (2022-01-01)
This paper presents an approach for concurrent power transfer to wired and wireless systems using just a single inverter. The approach utilizes a novel carrier phase-shift (CPS) method that independently controls the inverter output voltages at the fundamental and switching frequencies. This proposed method can be a cost-effective solution to wireless power transfer (WPT) systems used in contactless slip rings (CSR), which transfer power to auxiliary loads such as sensors, radars, and IoT devices. There are...

Eren, Merih; Bostancı, Emine; Department of Electrical and Electronics Engineering (2019)
Wireless power transfer (WPT) has been a very popular research topic for a variety of applications with power ratings ranging from few watts to several kilowatts. High power levels are mostly used in electric vehicle charging applications whereas lower power level applications are mostly in household appliances, wearable devices and medical implants. Topology, geometries of the transferring and receiving coils and their relative positions are fundamental parts that affect performance of WPT systems. In WPT ...
