Abstract: | A fractional lower-order, moment-based adaptive algorithm for estimating the time difference of arrival between signals received at two spatially 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 estimator. Convergence of the algorithm is analysed and simulation results are included to evaluate its estimation performance for both static and nonstationary delays |
