Intelligent reflecting surfaces (IRSs) are an emerging technology that enables tunable anomalous scattering of incident electromagnetic waves. This permits active control of the propagation environment and introduces an additional optimization dimension to wireless communication networks. A main use case is range extension and most recent work focuses on maximizing the received power over the IRS path. However, in [1] we have shown that power optimal IRS operation is also optimal in terms of Doppler spread and Pareto optimal when Delay spread is additionally considered.

The considered scenario in [1] assumes completely predicable receiver mobility and only a single transmitter-receiver pair. A possible application of this is the uplink of a ground terminal to a satellite in Low Earth Orbit. Several extensions of this scenario are suitable for projects and theses, e.g.,

  • extension to multiple fixed-position ground terminals;
  • random access protocols for massive IoT IRS assisted satellite uplink;
  • performance evaluation under statistical channel models and/or imperfectly known receiver trajectory;
  • optimal deployment and positioning of the IRS;
  • practical deployment aspects
All these topics are in the general area of communciation theory and require strong analytical skills. The thesis can be written in English or German.
