An overview of multirate multisensor systems: Modelling and estimation

Abstract

Abstract In this paper, research advances in modelling and estimation algorithms for multirate multisensor systems are reviewed. Multirate multisensor sampling schemes can be classified into two cases: uniform sampling and nonuniform sampling. A general method to solve an asynchronous estimation problem for multirate multisensor systems is to transform the asynchronous problem into a synchronous one. Then, synchronous estimation algorithms can be applied. Therefore, modelling synchronisation approaches are summarised for uniform and nonuniform sampling cases. Meanwhile, the corresponding estimation algorithms are reviewed according to different synchronised models. Last, future research topics are discussed.
