Research output: Contribution to journalArticlepeer-review


For the observation model "signal + white Gaussian noise", an on-line tracking algorithm for signal and its derivatives is proposed. The tracking algorithm applies to a class of signals with derivative up to the kth order. The asymptotic optimality in the minimax sense, with respect to small intensity of noise, is established.
