Throughput Analysis of Wireless Powered Cognitive Radio Networks with Compressive Sensing and Matrix Completion
Zhijin Qin, Yuanwei Liu, Yue Gao +2
In this paper, we consider a cognitive radio network in which energy constrained secondary users (SUs) can harvest energy from the randomly deployed power beacons (PBs). A new fram…
Non-orthogonal Multiple Access in Large-Scale Underlay Cognitive Radio Networks
Yuanwei Liu, Zhiguo Ding, Maged Elkashlan +1
In this paper, non-orthogonal multiple access (NOMA) is applied to large-scale underlay cognitive radio (CR) networks with randomly deployed users. In order to characterize the per…
Wireless Energy Harvesting in a Cognitive Relay Network
Yuanwei Liu, S. Ali Mousavifar, Yansha Deng +2
Wireless energy harvesting is regarded as a promising energy supply alternative for energy-constrained wireless networks. In this paper, a new wireless energy harvesting protocol i…
