Stochastic observability of linear systems under access constraints

This paper focuses on the stochastic observability of linear stochastic systems under access constraints, where the static communication strategy of governing the medium access by a communication sequence is adopted. The definition and criterion of stochastic observability of linear stochastic systems are discussed from information theoretic viewpoint. Analytic analysis shows that under access constraints there exists a communication sequence that can preserve the stochastic observability of the original linear system. Simulations illustrate our conclusion.
