Rao-Blackwellized particle filter for Markov modulated nonlinear dynamic systems

Saikat Saha, Gustaf Hendeby

Abstract: The Markov modulated (switching) state space is an important model paradigm in statistical signal processing. In this article, we specifically consider Markov modulated nonlinear state-space models and address the online Bayesian inference problem for such models. In particular, we propose a new Rao-Blackwellized particle filter for the inference task which is our main contribution here. A detailed description of the problem and an algorithm is presented.
