Corrections to "Computer Vision Aided mmWave Beam Alignment in V2X Communications"
Weihua Xu, Feifei Gao, Xiaoming Tao +2
In this document, we revise the results of [1] based on more reasonable assumptions regarding data shuffling and parameter setup of deep neural networks (DNNs). Thus, the simulatio…
Multi-User Matching and Resource Allocation in Vision Aided Communications
Weihua Xu, Feifei Gao, Yong Zhang +2
Visual perception is an effective way to obtain the spatial characteristics of wireless channels and to reduce the overhead for communications system. A critical problem for the vi…
Vision Aided Environment Semantics Extraction and Its Application in mmWave Beam Selection
Feiyang Wen, Weihua Xu, Feifei Gao +2
In this letter, we propose a novel mmWave beam selection method based on the environment semantics extracted from user-side camera images. Specifically, we first define the environ…
Vision-Aided Blockage Avoidance in UAV-assisted V2X Communications
Ruijin Ding, Weihua Xu, Wanmai Yuan +1
The blockage is a key challenge for millimeter wave communication systems, since these systems mainly work on line-of-sight (LOS) links, and the blockage can degrade the system per…
Computer Vision Aided mmWave Beam Alignment in V2X Communications
Weihua Xu, Feifei Gao, Xiaoming Tao +2
Visual information, captured for example by cameras, can effectively reflect the sizes and locations of the environmental scattering objects, and thereby can be used to infer commu…
Deep Learning Based Channel Covariance Matrix Estimation with User Location and Scene Images
Weihua Xu, Feifei Gao, Jianhua Zhang +2
Channel covariance matrix (CCM) is one critical parameter for designing the communications systems. In this paper, a novel framework of the deep learning (DL) based CCM estimation…
3D Scene Based Beam Selection for mmWave Communications
Weihua Xu, Feifei Gao, Shi Jin +1
In this paper, we present a novel framework of 3D scene based beam selection for mmWave communications that relies only on the environmental data and deep learning techniques. Diff…
