Performance Analysis of NOMA with Fixed Gain Relaying over Nakagami-m Fading Channels
Xinwei Yue, Yuanwei Liu, Shaoli Kang +1
This paper studies the application of cooperative techniques for non-orthogonal multiple access (NOMA). More particularly, the fixed gain amplify-and-forward (AF) relaying with NOM…
Energy-Efficient Mobile-Edge Computation Offloading for Applications with Shared Data
Xiangyu He, Hong Xing, Yue Chen +1
Mobile-edge computation offloading (MECO) has been recognized as a promising solution to alleviate the burden of resource-limited Internet of Thing (IoT) devices by offloading comp…
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…
Joint Altitude, Beamwidth, Location and Bandwidth Optimization for UAV-Enabled Communications
Zhaohui Yang, Cunhua Pan, Mohammad Shikh-Bahaei +4
This letter investigates an uplink power control problem for unmanned aerial vehicles (UAVs) assisted wireless communications. We jointly optimize the UAV's flying altitude, antenn…
Physical Layer Security in the Presence of Interference
Dimitrios S. Karas, Alexandros-Apostolos A. Boulogeorgos, George K. Karagiannidis
We evaluate and quantify the joint effect of fading and multiple interferers on the physical-layer (PHY) security of a system consisted of a base-station (BS), a legitimate user, a…
A Machine Learning Approach for Power Allocation in HetNets Considering QoS
Roohollah Amiri, Hani Mehrpouyan, Lex Fridman +3
There is an increase in usage of smaller cells or femtocells to improve performance and coverage of next-generation heterogeneous wireless networks (HetNets). However, the interfer…
Resource Allocation in NOMA based Fog Radio Access Networks
H. Zhang, Y. Qiu, K. Long +3
In the wake of growth in intelligent mobile devices and wide usage of bandwidth-hungry applications of mobile Internet, the demand of wireless data traffic and ubiquitous mobile br…
Modeling and Analysis of MmWave Communications in Cache-enabled HetNets
Wenqiang Yi, Yuanwei Liu, Arumugam Nallanathan
In this paper, we consider a novel cache-enabled heterogeneous network (HetNet), where macro base stations (BSs) with traditional sub-6 GHz are overlaid by dense millimeter wave (m…
Exploiting Multiple Access in Clustered Millimeter Wave Networks: NOMA or OMA?
Wenqiang Yi, Yuanwei Liu, Arumugam Nallanathan
In this paper, we introduce a clustered millimeter wave network with non-orthogonal multiple access (NOMA), where the base station (BS) is located at the center of each cluster and…
Outage Performance of Two-Way Relay Non-Orthogonal Multiple Access Systems
Xinwei Yue, Yuanwei Liu, Shaoli Kang +2
This paper investigates a two-way relay nonorthogonal multiple access (TWR-NOMA) system, where two groups of NOMA users exchange messages with the aid of one half-duplex (HD) decod…
Multiple Antenna Assisted Non-Orthogonal Multiple Access
Yuanwei Liu, Hong Xing, Cunhua Pan +3
Non-orthogonal multiple access (NOMA) is potentially capable of circumventing the limitations of the classic orthogonal multiple access schemes, hence it has recently received sign…
User Association and Resource Allocation in Unified NOMA Enabled Heterogeneous Ultra Dense Networks
Z. Qin, X. Yue, Y. Liu +2
Heterogeneous ultra dense networks (HUDNs) and non-orthogonal multiple access (NOMA) have been identified as two proposing techniques for the fifth generation (5G) mobile communica…
