Secrecy Analysis of Ambient Backscatter NOMA Systems under I/Q Imbalance
Xingwang Li, Mengle Zhao, Yuanwei Liu +3
We investigate the reliability and security of the ambient backscatter (AmBC) non-orthogonal multiple access (NOMA) systems, where the source aims to communication with two NOMA us…
Energy-Efficient Relay Selection and Optimal Relay Location in Cooperative Cellular Networks with Asymmetric Traffic
Wei Yang, Lihua Li, Wanlu Sun
Energy-efficient communication is an important requirement for mobile relay networks due to the limited battery power of user terminals. This paper considers energy-efficient relay…
Energy-Efficient Transmission Schemes in Cooperative Cellular Systems
Wei Yang, Lihua Li, Ying Wang +1
Energy-efficient communication is an important requirement for mobile devices, as the battery technology has not kept up with the growing requirements stemming from ubiquitous mult…
Joint Relay Selection and Link Adaptation for Distributed Beamforming in Regenerative Cooperative Networks
Wei Yang, Lihua Li, Gang Wu +1
Relay selection enhances the performance of the cooperative networks by selecting the links with higher capacity. Meanwhile link adaptation improves the spectral efficiency of wire…
Joint Uplink and Downlink Relay Selection in Cooperative Cellular Networks
Wei Yang, Lihua Li, Gang Wu +2
We consider relay selection technique in a cooperative cellular network where user terminals act as mobile relays to help the communications between base station (BS) and mobile st…
