N2 - The problem of direction of arrival (DOA) for multiple-input multiple-output (MIMO) array systems is considered, where orthogonal waveforms are transmitted simultaneously. A novel DOA estimation algorithm for collocated MIMO array is proposed. The proposed algorithm exploits the time delay to obtain two cross-correlation matrices, where the effect of additive noise is eliminated. Then we use singular value decomposition (SVD) technique to achieve the signal subspace matrix. Finally, an ESPRIT-like method is used to resolve the signal subspace and achieve the estimates of DOA. Simulation results confirm the effectiveness of the proposed algorithm.
