Incentive Mechanism Design for Wireless Energy Harvesting-Based Internet of Things
Zhanwei Hou, He Chen, Yonghui Li +1
Radio frequency energy harvesting (RFEH) is a promising technology to charge unattended Internet of Things (IoT) low-power devices remotely. To enable this, in future IoT system, b…
Short-Packet Two-Way Amplify-and-Forward Relaying
Yifan Gu, He Chen, Yonghui Li +2
This letter investigates an amplify-and-forward two-way relay network (TWRN) for short-packet communications. We consider a classical three-node TWRN consisting of two sources and…
Backscatter Multiplicative Multiple-Access Systems: Fundamental Limits and Practical Design
Wanchun Liu, Ying-Chang Liang, Yonghui Li +1
In this paper, we consider a novel ambient backscatter multiple-access system, where a receiver (Rx) simultaneously detects the signals transmitted from an active transmitter (Tx)…
Ultra-Reliable Short-Packet Communications: Half-Duplex or Full-Duplex Relaying?
Yifan Gu, He Chen, Yonghui Li +1
This letter analyzes and compares the performance of full-duplex relaying (FDR) and half-duplex relaying (HDR) for ultra-reliable short-packet communications. Specifically, we deri…
Iterative Receivers for Downlink MIMO-SCMA: Message Passing and Distributed Cooperative Detection
Weijie Yuan, Nan Wu, Qinghua Guo +3
The rapid development of the mobile communications requires ever higher spectral efficiency. The non-orthogonal multiple access (NOMA) has emerged as a promising technology to furt…
Hypergraph Theory: Applications in 5G Heterogeneous Ultra-Dense Networks
Hongliang Zhang, Lingyang Song, Yonghui Li +1
Heterogeneous ultra-dense network (HUDN) can significantly increase the spectral efficiency of cellular networks and cater for the explosive growth of data traffic in the fifth-gen…
