Localization and positioning of any subscriber in indoor environments on the basis of analysis of joint AOA-TOA signal distribution

This work presents theoretical and experimental analysis of radio signals propagation in LOS and NLOS indoor propagation conditions. Specifically, propagation conditions in straight corridor and adjacent rooms are analysed. Joint distribution of radio signals in the angle-of-arrival (AOA), time-of-arrival (TOA) and space domains is analyzed for the considered scenarios based on the modified stochastic multi-parametric approach, which combines guiding effects of the corridor with multi-scattering effects from obstructions inside the rooms. The multipath phenomena is analysed and an accurate fit between the theoretical and experimental results is demonstrated.
