Abstract: Adaptive array smart antenna involves the array processing to manipulate the signals induced on various antenna elements in such way that the main beam directing towards the desired signal and forming the nulls towards the interferers. Such smart antennas are widely used in wireless mobile communications as they can increase the channel capacity and coverage range. In adaptive array smart antenna, to locate the desired signal, various direction of arrival (DOA) estimation algorithms are used. This paper investigates Novel Snapshot Based approach using Estimation of Signal Parameters via Rotational Invariance Technique. ESPRIT algorithms provide high angular resolution and hence they are explored much in detail by varying various parameters of smart antenna system.
