This paper develops a new distributed power control scheme for a power-splitting-based interference channel (IFC) with simultaneous wireless information and power transfer (SWIPT). The considered IFC consists of multiple source–destination pairs. Each destination splits its received signal into two parts for information decoding (ID) and energy harvesting (EH), respectively. Each pair adjusts its...
We investigate the spectrum sharing problem of a radio frequency (RF)-powered cognitive radio network, where a multi-antenna secondary user (SU) harvests energy from RF signals radiated by a primary user (PU) to boost its available energy before information transmission. In this paper, we consider that both the PU and SU are rational and self-interested. Based on whether the SU helps forward the PU's...
