Publikováno v: Electronics Letters, Vol 59, Iss 24, Pp n/a-n/a (2023)
Abstract This paper proposes and experimentally evaluates, a reconfigurable intelligent surface (RIS) control system for multiple users using stereo camera images. The aim is to enable fast and fair received signal strength (RSS) beamforming for mult

Publikováno v: Frontiers in Communications and Networks, Vol 2 (2021)
As data rates demands are exploding, 5G will soon rely on mmWaves that offer much higher bandwidths. Yet at these frequencies, attenuation and diffraction of waves require point to point communications with beamforming base stations that are complex
