Using the Kalman filtering method, the time-varying optimal dis- tributed fusion white noise deconvolution estimator is presented for the multisensor linear discrete time-varying systems. It is derived from the centralized fusion white noise deconvolution estimator so that it is identical to the centralized fuser, i.e., it has the global optimality. It is superior to the existing distributed fusion white noise estimators in the optimality and the complexity of computation. A Monte Carlo simulation for the Bemoulli- Gaussian input white noise shows the effectiveness of the proposed results.展开更多
