Abstract

Rapidly growing demand in mobile communication system required technology which will provide minimum errors and maximize SNR in a particular angle/direction. Smart antenna has a system for directed a beam towards desired angle/direction and suppress/cancel interference from undesired angle/direction. MUSIC (Multiple Signal Classification) has capability to estimate number of signals in an array and angle/direction of arrival of desired signal. ESPRIT (Estimation of Signal Parameters via Rotational Invariance Techniques) is used for the estimation of direction of arrival of multiple sets of identical doublets, provides parallel processing. This Paper provides comparative analysis and simulation of angle of arrival (AOA) estimation, and estimate error in AOA estimation. Relative results are useful for achieving optimal performance in smart antenna design.
