Bayesian Simultaneous Localization and Mapping with Non-Ideal Reflective Surfaces

Accurate indoor localization using radio signals exchanged between base stations (BSs) and mobile dives (such as mobile phones) remains a challenging issue. This capability is essential for various critical applications, including search-and-rescue operations and autonomous navigation. We have recently developed a Bayesian particle-based sum–product algorithm (SPA) for multipath-based simultaneous localization and mapping [1, 2] that accounts for non-ideal reflective surfaces by jointly estimating dispersion parameters for individual physical and virtual anchors. This thesis provides the opportunity to work on state-of-the-art Bayesian inference methods for next-generation wireless localization systems.

Your Task

  • Extend and improve the current dispersion model based on [1, 2].
  • Test and evaluate the algorithm using real measured radio signals from a dataset provided by our lab.

Your Profile

  • Familiar with (statistical) signal processing.
  • Inclined to do theoretical/simulation based work.
  • Experience with python or matlab is beneficial.
