Multiple Bayesian Filtering as Message Passing
Giorgio M. Vitetta, Pasquale Di Viesti, Emilio Sirignano +1
In this manuscript, a general method for deriving filtering algorithms that involve a network of interconnected Bayesian filters is proposed. This method is based on the idea that…
Parallel Concatenation of Bayesian Filters: Turbo Filtering
Giorgio M. Vitetta, Pasquale Di Viesti, Emilio Sirignano +1
In this manuscript a method for developing novel filtering algorithms through the parallel concatenation of two Bayesian filters is illustrated. Our description of this method, cal…
Rao-Blackwellized Particle Smoothing as Message Passing
Giorgio M. Vitetta, Emilio Sirignano, Francesco Montorsi
In this manuscript the fixed-lag smoothing problem for conditionally linear Gaussian state-space models is investigated from a factor graph perspective. More specifically, after fo…
Marginalized Particle Filtering and Related Filtering Techniques as Message Passing
Giorgio M. Vitetta, Emilio Sirignano, Francesco Montorsi +1
In this manuscript a factor graph approach is employed to investigate the recursive filtering problem for a mixed linear/nonlinear state-space model, i.e. for a model whose state v…
Design and Implementation of an Inertial Navigation System for Pedestrians Based on a Low-Cost MEMS IMU
Francesco Montorsi, Fabrizio Pancaldi, Giorgio M. Vitetta
Inertial navigation systems for pedestrians are infrastructure-less and can achieve sub-meter accuracy in the short/medium period. However, when low-cost inertial measurement units…
Map-Aware Models for Indoor Wireless Localization Systems: An Experimental Study
Francesco Montorsi, Fabrizio Pancaldi, Giorgio M. Vitetta
The accuracy of indoor wireless localization systems can be substantially enhanced by map-awareness, i.e., by the knowledge of the map of the environment in which localization sign…
On the Performance Limits of Map-Aware Localization
Francesco Montorsi, Santiago Mazuelas, Giorgio M. Vitetta +1
Establishing bounds on the accuracy achievable by localization techniques represents a fundamental technical issue. Bounds on localization accuracy have been derived for cases in w…
Statistical Characterization and Mitigation of NLOS Bias in UWB Localization Systems
Francesco Montorsi, Fabrizio Pancaldi, Giorgio M. Vitetta
Propagation in non-line-of-sight (NLOS) conditions is one of the major impairments in ultrawideband (UWB) wireless localization systems based on time-of-arrival (TOA) measurements.…
Statistical Characterization and Mitigation of NLOS Errors in UWB Localization Systems
Francesco Montorsi, Fabrizio Pancaldi, Giorgio M. Vitetta
In this paper some new experimental results about the statistical characterization of the non-line-of-sight (NLOS) bias affecting time-of-arrival (TOA) estimation in ultrawideband…
On the Performance Limits of Pilot-Based Estimation of Bandlimited Frequency-Selective Communication Channels
Francesco Montorsi, Giorgio M. Vitetta
In this paper the problem of assessing bounds on the accuracy of pilot-based estimation of a bandlimited frequency selective communication channel is tackled. Mean square error is…
