As the computer hardware developing and the fast advances of computers in the last several years, Monte Carlo particle filter algorithms, which origin Monte Carlo methods, have become popular again. The Monte Carlo particle filter algorithms in this paper use the concepts of sequential importance sampling. The base idea of particle filter is the approximation of relevant probability distributions using a set of discrete random samples with associated weights.
