  The IEEE Signal Processing Society is proud to announce the eighth edition of
the Signal Processing Cup: an exciting challenge to control a wireless
propagation environment using an intelligent reflecting surface.
  An intelligent reflecting surface is a two-dimensional array of metamaterial
whose interaction with electromagnetic waves can be controlled, e.g., by tuning
the impedance variations over the surface. These surfaces might be used in the
sixth generation (6G) mobile technology to direct wireless signals from a
transmitter towards a receiver, to raise the communication performance. The
goal of the challenge is to characterize the behavior of an intelligent
reflecting surface based on received signals from an over-the-air signaling
phase and develop a control algorithm to configure the surface to aid wireless
communications.
