Wideband Direction of Arrival Estimation based on Fourth-order Cumulants
Based on MUSIC (MUltiple SIgnal Classification) algorithm and CSM (Coherent Signal- subspace Method), a DOA estimation method of wideband signals has been proposed in this paper. At first, the output covariance matrix is formed based on the fourth-order cumulants using the relation between the fourth-order and the covariance. And then using the projector operator to form focusing matrix and estimate the DOA of wideband signals with focused covariance matrix and MUSIC algorithm.. This algorithm can suppress Gaussian noise to improve the precision of DOA estimation. It does not need pre-estimation of DOA in focusing processing to improve the speed of the algorithm.
