In order to solve the state estimation problem with non-Gaussian measurement, an adaptive filtering algorithm is proposed. The measurement noise is modeled by the heavy-tailed distribution. The variational Bayesian algorithm can be used to estimate the parameter of the measurement noise and the system state. Simulation results are presented to demonstrate the versatility and improved performance of the proposed adaptive filter over conventional Kalman filters and the lower complexity than the particle filters.
