Intelligent Reflecting Surface Aided Vehicular Communications [PDF]

open access: yes2020 IEEE Globecom Workshops (GC Wkshps, 2020
We investigate the use of an intelligent reflecting surface (IRS) in a millimeter-wave (mmWave) vehicular communication network. An intelligent reflecting surface consists of passive elements, which can reflect the incoming signals with adjustable phase shifts. By properly tuning the phase shifts we can improve link performance.
