Optimal linear estimation fusion
WebFirst, we formulate the problem of distributed esti- mation fusion in a general setting of best linear unbiased estimation (BLUE), also known as linear unbiased least mean-square (LMS) estimation. For unbiased local esti- mators, the linear, unbiased fused estimator of the small- est mean-square error is their weighted sum with a matrix weight. WebThe optimality (equivalence to the optimal centralized estimation fusion) of the new optimal distributed estimation fusion algorithm is analyzed and a necessary and sufficient …

IEEE Trans Automat Contr, 1981, 26: 571–572 WebThis paper discusses the equivalence of the performance between the optimal distributed and centralized fusion based on best linear unbiased estimation (BLUE). A necessary and sufficient condition for the optimal distributed BLUE fusion to have identical performance as their centralized counterparts is obtained by setting the difference of two optimal …
WebJun 1, 2024 · In this paper, we consider optimal linear sensor fusion for obtaining a remote state estimate of a linear process based on the sensor data transmitted over lossy channels. There is no local observability guarantee for any of the sensors. It is assumed that the state of the linear process is collectively observable. Webtrix for performance degradation of the optimal distributed fusion relative to the optimal centralized fusion are given. It is shown both theoretically and by simulation results that …
WebBased on the best linear unbiased estimation (BLUE) fusion results obtained in the previous parts of this series, in this paper we present optimal rules for compressing data at each local sensor to an allowable size (i.e., dimension) such that the fused estimate is optimal.
