This letter considers secrecy simultaneous wireless information and power transfer (SWIPT) in full-duplex (FD) systems. In such a system, FD capable base station (FD-BS) is designed to transmit data to one downlink user and concurrently receive data from one uplink user, while one idle user harvests the radio-frequency (RF) signals' energy to extend its(More)
In this paper, an energy harvesting (EH) based cooperative non-orthogonal multiple access (NOMA) system is considered, where node S simultaneously sends independent signals to a stronger node R and a weaker node D. We focus on the scenario that the direct link between S and D is too weak to meet the quality of service (QoS) of D. Based on the NOMA(More)

Cloud Radio Access Network (C-RAN) architecture with optical fiber fronthaul has been confirmed as a promising solution to achieve high capacity and low latency signal transmission, which has been a key technology and trend of the evolving fifth generation (5G) cellular networks. However, with the fiber fronthaul increasing, the complexity and cost of the(More)
