| Abstract: | To the fusion problem of backward filtering and deconvolution of stochastic systems with multiplicative noise and observed by multisensor, an optimal fusion algorithm is provided. The optimum of this algorithm is based on maximum likelihood sense. The algorithm is used in a parallel way among each sensor and there is no backward communication from the fusion center to the processing center of single sensor. So it has a better efficiency of computation. Simulation shows that the backward filtering and deconvolution computed by this fusion algorithm have an obvious improvement to those resulted from single sensor's processing. |
