One-Dimensional Ionic-Bonded Structures in NiSe Nanowire

Autor: Liu, Xiaozhi, Gao, Ang, Zhang, Qinghua, Wang, Yaxian, Zhang, Yangyang, Li, Yangfan, Zhang, Xing, Gu, Lin, Hu, Jinsong, Su, Dong

One-dimensional van der Waals (1D vdW) materials, characterized by atomic chains bonded ionically or covalently in one direction and held together by van der Waals interactions in the perpendicular directions, have recently gained intensive attention

SPQE: Structure-and-Perception-Based Quality Evaluation for Image Super-Resolution

Autor: Zhang, Keke, Zhao, Tiesong, Chen, Weiling, Niu, Yuzhen, Hu, Jinsong

The image Super-Resolution (SR) technique has greatly improved the visual quality of images by enhancing their resolutions. It also calls for an efficient SR Image Quality Assessment (SR-IQA) to evaluate those algorithms or their generated images. In

Hybrid Relay-Reflecting Intelligent Surface-Aided Covert Communications

Autor: Hu, Jinsong, Shi, Xiaoqiang, Chen, Youjia, Zhao, Tiesong, Shu, Feng

In this paper, we propose to use a hybrid relay-reflecting intelligent surface (HR-RIS) to enhance the performance of a covert communication system. Specifically, the HR-RIS consists of passive reflecting elements and active relay elements to manipul

Machine Learning Methods for Inferring the Number of UAV Emitters via Massive MIMO Receive Array

Autor: Li, Yifan, Shu, Feng, Hu, Jinsong, Yan, Shihao, Song, Haiwei, Zhu, Weiqiang, Tian, Da, Song, Yaoliang, Wang, Jiangzhou

To provide important prior knowledge for the DOA estimation of UAV emitters in future wireless networks, we present a complete DOA preprocessing system for inferring the number of emitters via massive MIMO receive array. Firstly, in order to eliminat
