A Frequency - Delay of Arrival (FDOA) estimation algorithm based on Fourth - Order Cumulant is discussed. The realization of the algorithm is given. With the characteristic of high order cumulant, the algorithm can accurately estimate the FDOA under correlated noise condition. Simulation result proves its effeciency.
