Joint Channel Estimation and Data Detection for Hybrid RIS aided Millimeter Wave OTFS Systems
Muye Li, Shun Zhang, Yao Ge +2
For high mobility communication scenario, the recently emerged orthogonal time frequency space (OTFS) modulation introduces a new delay-Doppler domain signal space, and can provide…
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…
Integrated Sensing and Communications with Joint Beam Squint and Beam Split for Massive MIMO
