—This paper proposes a belief propagation (BP)-based algorithm for sequential detection and estimation of multipath component (MPC) parameters based on radio signals. Under dynamic channel conditions with moving transmitter/receiver, the number of MPCs, the MPC dispersion parameters, and the number of false alarm contributions are unknown and time-varying. We develop a Bayesian model for sequential detection and estimation of MPC dispersion parameters, and represent it by a factor graph… 
A Graph-based Algorithm for Robust Sequential Localization Exploiting Multipath for Obstructed-LOS-Bias Mitigation
TLDR
A novel non-uniform false alarm model is derived that captures the delay and amplitude statistics of the multipath radio channel and enables the algorithm to indirectly exploit position-related information contained in the MPCs for the estimation of the agent position.
