Path Planning for the Dynamic UAV-Aided Wireless Systems using Monte Carlo Tree Search
Yuwen Qian, Kexin Sheng, Chuan Ma +3
For UAV-aided wireless systems, online path planning attracts much attention recently. To better adapt to the real-time dynamic environment, we, for the first time, propose a Monte…
Federated Learning Over Wireless Channels: Dynamic Resource Allocation and Task Scheduling
Shunfeng Chu, Jun Li, Jianxin Wang +5
With the development of federated learning (FL), mobile devices (MDs) are able to train their local models with private data and sends them to a central server for aggregation, the…
UAV-enabled Secure Communication with Finite Blocklength
Yuntian Wang, Xiaobo Zhou, Zhihong Zhuang +4
In the finite blocklength scenario, which is suitable for practical applications, a method of maximizing the average effective secrecy rate (AESR) is proposed for a UAV-enabled sec…
User Association and Path Planning for UAV-Aided Mobile Edge Computing with Energy Restriction
Yuwen Qian, Feifei Wang, Jun Li +3
Mobile edge computing (MEC) provides computational services at the edge of networks by offloading tasks from user equipments (UEs). This letter employs an unmanned aerial vehicle (…
An Efficient Hybrid Beamforming Design for Massive MIMO Receive Systems via SINR Maximization Based on an Improved Bat Algorithm
Mohammed A. Almagboul, Feng Shu, Yaolu Qin +4
Hybrid analog and digital (HAD) beamforming has been recently receiving considerable deserved attention for a practical implementation on the large-scale antenna systems. As compar…
Power Allocation Strategies for Secure Spatial Modulation
Guiyang Xia, Linqiong Jia, Yuwen Qian +3
In secure spatial modulation (SM) networks, power allocation (PA) strategies are investigated in this paper under the total power constraint. Considering that there is no closed-fo…
