Distributed Reconfigurable Intelligent Surfaces for Energy Efficient Indoor Terahertz Wireless Communications

no code implementations12 Oct 2022 Yiming Huo, Xiaodai Dong, Nuwan Ferdinand

Furthermore, we propose a distributed RISs framework (DRF) to assist the indoor THz wireless communication to achieve overall energy efficiency.

Wi-Fi and Bluetooth Contact Tracing Without User Intervention

no code implementations31 Mar 2022 Brosnan Yuen, Yifeng Bie, Duncan Cairns, Geoffrey Harper, Jason Xu, Charles Chang, Xiaodai Dong, Tao Lu

Previous contact tracing systems required the users to perform many manual actions, such as installing smartphone applications, joining wireless networks, or carrying custom user devices.

Meteorologically Introduced Impacts on Aerial Channels and UAV Communications

no code implementations14 Apr 2021 Mengan Song, Yiming Huo, Tao Lu, Xiaodai Dong, Zhonghua Liang

As 5G wireless systems and networks are now being globally commercialized and deployed, more diversified application scenarios are emerging, quickly reshaping our societies and paving the road to the beyond 5G (6G) era when terahertz (THz) and unmanned aerial vehicle (UAV) communications may play critical roles.

Universal Activation Function For Machine Learning

no code implementations7 Nov 2020 Brosnan Yuen, Minh Tu Hoang, Xiaodai Dong, Tao Lu

This article proposes a Universal Activation Function (UAF) that achieves near optimal performance in quantification, classification, and reinforcement learning (RL) problems.

QoS-Compliant 3D Deployment Optimization Strategy for UAV Base Stations

no code implementations7 Aug 2020 Xukai Zhong, Yiming Huo, Xiaodai Dong, Zhonghua Liang

Although there has been quite some prior research on the UAV deployment, no work has studied this problem in a 3 dimensional (3D) setting and taken into account the UAV-BS capacity limit and the quality of service (QoS) requirements of ground users.

Deep Q-Network Based Dynamic Movement Strategy in a UAV-Assisted Network

no code implementations7 Aug 2020 Xukai Zhong, Yiming Huo, Xiaodai Dong, Zhonghua Liang

Then a deep Q-network (DQN) based method is proposed to adjust the locations of UAVs to maximize the sum data rate of the user equipment (UE).

A CNN-LSTM Quantifier for Single Access Point CSI Indoor Localization

no code implementations13 May 2020 Minh Tu Hoang, Brosnan Yuen, Kai Ren, Xiaodai Dong, Tao Lu, Robert Westendorp, Kishore Reddy

This paper proposes a combined network structure between convolutional neural network (CNN) and long-short term memory (LSTM) quantifier for WiFi fingerprinting indoor localization.

Semi-Sequential Probabilistic Model For Indoor Localization Enhancement

no code implementations8 Jan 2020 Minh Tu Hoang, Brosnan Yuen, Xiaodai Dong, Tao Lu, Robert Westendorp, Kishore Reddy

In contrast, SSP leverages the information of the previous position to determine the probable location since the user's speed in an indoor environment is bounded and locations near the previous one have higher probability than the other locations.
