In this paper a comparison of the performance of three famous Eigen structure based Direction of arrival (DOA) algorithms known as the Multiple Signal Classification (MUSIC), the Estimation of Signal Parameter via Rotational Invariance Techniques (ESPRIT) and a non-subspace method maximum-likelihood estimation (MLE) has been extensively studied in this research work The performance of this DOA estimation algorithm based on Uniform Linear Array (ULA). We estimated various DOA using MATLAB, results shows that MUSIC algorithm is more accurate and stable compared to ESPRIT and MLE algorithms.
