| Abstract: |
| 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. |
