    Abstract: This article addresses the joint estimation of parameters and states in linear stochastic systems with correlated process and measurement noises. We propose the Kalman Filtering with Correlated Noises based Recursive Generalized Extended Least Squares (KF-CN-RGELS) algorithm, which innovatively integrates a reformulated Kalman filter to handle nois...

    Abstract: Let G be an n-regular graph. A sequentially perfect one-factorization is a decomposition of G into one-factors, such that union of any two consecutive one-factors gives a hamiltonian cycle, and also if the union of two consecutive one-factors forms a two regular graph, then this property is termed as sequentially uniform. For any two graphs G and H... Show More
