Distributed Beamforming in MISO SWIPT System

IEEE Transactions on Vehicular Technology, 2017
In previous works on simultaneous wireless information and power transfer (SWIPT) multiple-input single-output (MISO) system with multiple users, beamforming requires all the transmitters know the channel state information (CSI) of the whole system. We relax it so that it is a practical assumption: Each transmitter only knows its own CSI to all the ...

On the Performance of Regenerative Relaying for SWIPT in NOMA Systems [PDF]

2019 26th International Conference on Telecommunications (ICT), 2019
As a potential access strategy in 5G mobile communication systems, non-orthogonal multiple access (NOMA) has been proposed as a supplement to the traditional orthogonal multiple access (OMA). This paper investigates simultaneous wireless information and power transfer (SWIPT) in a NOMA relaying system.
