Abstract :
A new method is presented for estimating DOA using the independence of signals. This method can be tracked the subspace of the independence signal and avoided obtaining the noise subspace which is presented in some papers. The independent characteristics obtained by the critical of MMSE can be reflected the changing of signal angle.
