Basha, P. Sridevi, M. Prasad] Smart antenna is now commonly used in communication systems due to its high advantages. In order to improve the performance of smart antenna operation, efficient design of beam forming pattern is required based on the subjected antenna parameters. In the previous works, beam forming techniques were proposed using hybridization of soft computing techniques, however the precision has not been considered in terms of direction of arrival (DOA). This paper includes DOA while deriving the beam forming pattern of smart antenna. To estimate precise DOA, the MUSIC algorithm is improved by introducing a tuned correlation matrix after solving the objective model for the matrix. Thus estimated DOA pattern is more precise as the unwanted side lobes are suppressed when compared to the conventional DOA pattern. Based on the estimated DOA pattern, the antenna beam forming pattern is derived as per the required direction of angles. The experimental results show the performance of the proposed beam forming technique over the previous techniques.
