This paper is concerned with the optimal Markov jump linear filter problem for Markov jumping parameter system with multi-channel observation delays and packet losses, where the jumping parameters are assumed to be known up to the present time. Firstly, by defining an equivalent delay-free observation sequence, the optimal jumping filter problem is transformed into the one of delay-free system which...
Range-based positioning by estimating the time of arrival (ToA) of the line-of-sight (LoS) path using orthogonal frequency-division multiplexing (OFDM) signals has gained remarkable attention. Multipath propagation significantly influences the ToA estimate, resulting in position errors. To mitigate these errors, the multipath channel needs to be accurately estimated, usually with a large number of...
This paper is to develop a new distributed estimation technique for linear systems with network induced delays and packet dropouts. A set of random variables are utilized to model the random delay phenomena occurring in the channels from the system to the sensors. And the consensus weights are assumed to be known. A distributed sub-optimal filter is presented by minimizing an upper bound on a quadratic...
