Centralized, distributed and sequential fusion estimation from uncertain outputs with correlation between sensor noises and signal Caballero-Águila, Raquel Hermoso-Carazo, Aurora Linares-Pérez, Josefa Centralized fusion estimation Distributed fusion estimation Sequential fusion estimation Covariance information Random measurement matrices This paper focuses on the least-squares linear fusion filter design for discrete-time stochastic signals from multisensor measurements perturbed not only by additive noise, but also by different uncertainties that can be comprehensively modeled by random parameter matrices. The additive noises from the different sensors are assumed to be cross-correlated at the same time step and correlated with the signal at the same and subsequent time steps. A covariancebased approach is used to derive easily implementable recursive filtering algorithms under the centralized, distributed and sequential fusion architectures. Although centralized and sequential estimators both have the same accuracy, the evaluation of their computational complexity reveals that the sequential filter can provide a significant reduction of computational cost over the centralized one. The accuracy of the proposed fusion filters is explored by a simulation example, where observation matrices with random parameters are used to describe different kinds of sensor uncertainties. 2021-03-23T07:20:12Z 2021-03-23T07:20:12Z 2019-09 journal article http://hdl.handle.net/10481/67456 https://doi.org/10.1080/03081079.2019.1659257 eng http://creativecommons.org/licenses/by-nc-nd/3.0/es/ embargoed access Atribución-NoComercial-SinDerivadas 3.0 España Taylor&Francis
