Short Description

In previous work, multipath assisted indoor localization and tracking (MINT) was introduced as a localization method which is inherently robust to multipath propagation. This is due to the fact that multipath is explicitly used as localization information. However, up to now, base stations (anchors) and mobile have been assumed to be perfectly synchronized. This is not feasible in practice. The goals of this thesis are:

  • Theoretical evaluation of the impact of missing synchronization by use of Cramer-Rao bounds
  • Verification of the results using simulations and possibly measured signals
  • Derivation and analysis of suitable synchronization methods.
