Abstract：When the noises are spatially correlated, the time delay methods based on second order statistic will be useless. In this paper a kind of adaptive time delay estimation method based on third order statistic is provided, and its convergence is analyzed. Finally , simulation results demonstrate that this approach can effectively depress Gaussian correlated noise.
