A new DOA or AOA estimation algorithm for multipath signals based on synchronous CDMA frequency-selective fading channel based on the main eigenvector of the covariance matrix is proposed. The proposed algorithm has the ability to eliminate the interference of other multipath signals To estimate the expected signal arrival angle.The simulation results show that the algorithm can efficiently and accurately estimate the arrival angle of multipath signals
