Vision-Aided Blockage Avoidance in UAV-assisted V2X Communications

no code implementations26 Jul 2022 Ruijin Ding, Weihua Xu, Wanmai Yuan, Feifei Gao

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 performance significantly.

Computer Vision Aided mmWave Beam Alignment in V2X Communications

no code implementations23 Jul 2022 Weihua Xu, Feifei Gao, Xiaoming Tao, Jianhua Zhang, Ahmed Alkhateeb

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 communications parameters like propagation directions, receiver powers, as well as the blockage status.
