Efficient wideband signals’ direction of arrival estimation method with unknown number of signals
This article focuses on the direction of arrival estimation of wideband signals, and an efficient method based on test of orthogonality of frequency subspaces is proposed. Using suitable coefficient m to weight and inverse the covariance matrix, the proposed method can obtain estimated noise subspac...
