摘要

A novel method is presented to jointly estimate the directions of arrival (DOAs) and the propagation delays of multipath signals in wireless communications. The proposed method makes use of the eigenvectors of the space-time matrix to estimate DOAs and the eigenvalues of the space-time matrix to estimate delays, respectively. At the same time, the estimated DOAs and delays are automatically determined by the relationship between the eigenvalue and the eigenvector. Compared with the previous work, the proposed method can provide better performance with substantially reduced computational complexity. Simulation results show the effectiveness of the space-time matrix method.
