Enhanced DOA estimation algorithms using MVDR and MUSIC

This paper introduces a comparative study between two algorithms for Direction-of-Arrival (DOA) estimation which are MVDR (Minimum Variance Distortionless Response) and MUSIC (Multiple Signal classification). The used algorithms are used for Direction-of-Arrival (DOA) estimation in smart antenna. The paper presents a comparative study for both algorithms in terms of the total mobile users number, effect of signal parameters, spacing between adjacent elements, and number of snapshots. It is proven that MUSIC has better performance than MVDR algorithm. MUSIC algorithm is more effective and introduces more enhancing performance.
