Ziv-Zakai Bound for DOAs Estimation
Zongyu Zhang, Zhiguo Shi, Yujie Gu
Lower bounds on the mean square error (MSE) play an important role in evaluating the direction-of-arrival (DOA) estimation performance. Among numerous bounds for DOA estimation, th…
Global and Asymptotically Efficient Localization from Range Measurements
Guangyang Zeng, Biqiang Mu, Jiming Chen +2
We consider the range-based localization problem, which involves estimating an object's position by using sensors, hoping that as the number of sensors increases, the estim…
FTPipeHD: A Fault-Tolerant Pipeline-Parallel Distributed Training Framework for Heterogeneous Edge Devices
Yuhao Chen, Qianqian Yang, Shibo He +2
With the increased penetration and proliferation of Internet of Things (IoT) devices, there is a growing trend towards distributing the power of deep learning (DL) across edge devi…
You foot the bill! Attacking NFC with passive relays
Yuyi Sun, Swarun Kumar, Shibo He +2
Imagine when you line up in a store, the person in front of you can make you pay her bill by using a passive wearable device that forces a scan of your credit card without your awa…
Connectivity of Underlay Cognitive Radio Networks with Directional Antennas
Qiu Wang, Hong-Ning Dai, Orestis Georgiou +2
In cognitive radio networks (CRNs), the connectivity of secondary users (SUs) is difficult to be guaranteed due to the existence of primary users (PUs). Most prior studies only con…
Doppler-Radar Based Hand Gesture Recognition System Using Convolutional Neural Networks
Jiajun Zhang, Jinkun Tao, Jiangtao Huangfu +1
Hand gesture recognition has long been a hot topic in human computer interaction. Traditional camera-based hand gesture recognition systems cannot work properly under dark circumst…
Deformable Deep Convolutional Generative Adversarial Network in Microwave Based Hand Gesture Recognition System
Jiajun Zhang, Zhiguo Shi
Traditional vision-based hand gesture recognition systems is limited under dark circumstances. In this paper, we build a hand gesture recognition system based on microwave transcei…
Re-DPoctor: Real-time health data releasing with w-day differential privacy
Jiajun Zhang, Xiaohui Liang, Zhikun Zhang +2
Wearable devices enable users to collect health data and share them with healthcare providers for improved health service. Since health data contain privacy-sensitive information,…
