Low-Power Wide-Area Networks for Sustainable IoT
Zhijin Qin, Frank Y. Li, Geoffrey Ye Li +2
Low-power wide-area (LPWA) networks are attracting extensive attention because of their abilities to offer low-cost and massive connectivity to Internet of Things (IoT) devices dis…
Resource Allocation in Wireless Powered IoT Networks
Xiaolan Liu, Zhijin Qin, Yue Gao +1
In this paper, efficient resource allocation for the uplink transmission of wireless powered IoT networks is investigated. We adopt LoRa technology as an example in the IoT network…
UAV Communications Based on Non-Orthogonal Multiple Access
Yuanwei Liu, Zhijin Qin, Yunlong Cai +3
This article proposes a novel framework for unmaned aerial vehicle (UAV) networks with massive access capability supported by non-orthogonal multiple access (NOMA). In order to bet…
Non-Orthogonal Multiple Access for 5G and Beyond
Yuanwei Liu, Zhijin Qin, Maged Elkashlan +3
Driven by the rapid escalation of the wireless capacity requirements imposed by advanced multimedia applications (e.g., ultra-high-definition video, virtual reality etc.), as well…
Deep Learning in Physical Layer Communications
Zhijin Qin, Hao Ye, Geoffrey Ye Li +1
Deep learning (DL) has shown the great potentials to break the bottleneck of communication systems. This article provides an overview on the recent advancements in DL-based physica…
Outage Performance of A Unified Non-Orthogonal Multiple Access Framework
Xinwei Yue, Zhijin Qin, Yuanwei Liu +2
In this paper, a unified framework of non-orthogonal multiple access (NOMA) networks is proposed, which can be applied to code-domain NOMA (CD-NOMA) and power-domain NOMA (PD-NOMA)…
