Abstract

This paper presents a simulation tool for direction-of-arrival (DOA) estimation in adaptive signal processing arrays. The tool implements the multiple signal classification (MUSIC) DOA algorithm. A user-friendly graphical user interface (GUI) is also developed. In addition to its usefulness in the design and analysis of adaptive signal processing arrays, the tool can also be used for computer-aided learning of modem communication systems utilizing smart antennas. To demonstrate the versatility and accuracy of the developed tool, it is used to carry out a detailed performance analysis of DOA estimation using MUSIC. This includes investigating the effect of the number of mobile users and their spatial distribution, the number of array elements and their spacing, and the number of signal snapshots.
