The smart antennas are widely used for wireless communication; because it has ability to increase the coverage, reduce the interference & increase the capacity of a communication system and low complexity DOA estimation algorithms can be applied to decrease the required computational complexity. A Smart antenna system is used to maximize the output power of signal in desired direction and minimize the power in unwanted direction. Beamforming is a technique which is used in smart antennas for enhanced signal transmission and reception. In this paper we studied and analyzed different beamforming methods. During survey of work we have found that different authors have developed separate methods to solve the purpose. So we conclude that there is not any unique method in this regard. Hence in this work we come across to develop a new adaptive beamforming algorithm for smart antenna to solve the purpose using MATLAB.
