Abstract :
In this paper, we use the Gibbs sampler to carry out Bayesian inference on conditionally linear Gaussian state space models. In a Bayesian framework, the Gibbs sampler is a powerful iterative procedure which can be seen as a stochastic analogue of the EM algorithm. To use it, it is necessary to sample from complex multivariate densities. An efficient algorithm is derived. An application to Bernoulli-Gauss processes deconvolution is given for which very satisfactory results are obtained. For this example, the geometric convergence of the algorithm is established
