Resumo

Smart antenna is now commonly used in communication systems due to its high advantages. Two important functions in smart antenna are direction of arrival estimation and beam forming. The main aim of direction of arrival estimation in smart antenna is to estimate the direction of the signal and based on this angle the beam forming will identify the exact position and phase angle of the antenna. Here we proposed a new MUSIC algorithm for direction of arrival method to improve the performance of smart antenna. The proposed method uses genetic algorithm and neural network for direction of arrival estimation and beam forming. By using this method, the interference signal reduces and also the performance of the system increases.  Keywords: Smart antenna, direction of arrival, beam forming, genetic algorithm, neural network.
