Abstract—For the problem of estimation time-difference-ofarrival (TDOA) for cyclostationary signals in the presence of interference and impulsive noise, a new robust multicycle signal-selective algorithm is introduced. By fusing second-order cyclic moments and fractional lower-order statistics, a novel cyclic fractional lower-order statistics is developed. The proposed algorithm combines the benefits of cyclostationarity based method and fractional lower-order statistics based estimator, by exploiting cyclostationarity property of signals with cyclic fractional lower-order statistics. Simulation results indicate that the new method is highly tolerant to interference and impulsive noise and gives higher estimation accuracy than conventional TDOA estimation methods.

Index Terms—Cyclostationarity, impulsive noise, fractional lower-order statistics, time-difference-of-arrival (TDOA).
