Abstract Independent component analysis aims to find a linearly transformation to coordinates in which the data are maximally statistical independent. In the method, by using the independent vector basis, the mixed signal will be decomposed to the independent components. Under some conditions, it is equivalent to the blind source separation. In this paper, the independent vector basis can be got by using the nonlinear minimizing mean square criterion. It can estimate the DOA of ULA by using the character of the independent vector basis.
