DOA Estimation Method Based on Blind Signal Separation
Nan Qin-bo · Journal of Air Force Engineering University · 2010
To apply the blind signal separation method to DOA estimation,the blind signal separation(BSS) algorithm based on fast fixed-point independent component analysis is introduced in this paper.By using this algorithm,the estimation of manifold matrix is deduced from the gained separated matrix.We obtain the DOA(direction-of-arrival) of signals from angle scaling based on the projection of the column vector on the real array configuration.The results of the experiment show that this algorithm has good resolution in a low SNR(Signal Noise Ratio) environment compared with the MUSIC(Multiple Signal Classification) algorithm.
