ADAPTIVE TDOA ESTIMATION IN PRESENCE OF IMPULSIVE NOISE

A fractional lower-order, moment-based adaptive algorithm for estimati ng the time difference of arrival between signals received at two spat ially separated sensors in the presence of impulsive noise modelled as a stable process is proposed. The method is computationally efficient and is a generalisation of the simplified explicit time delay estimat or. Convergence of the algorithm is analysed and simulation results ar e included to evaluate its estimation performance for both static and nonstationary delays.
