In recent years there has been rapid growth in the area of wireless communication. This demands for more system capacity and also reduction in interference as low as possible. This leads to the application of Smart Antenna (array of antenna and signal processing) in wireless communication, which increases channel capacity, range coverage and reduces interference. This is achieved through the DOA (Direction Of Arrival) estimation and Beamforming technique. In DOA estimation, the direction in which the array has maximum response for the desired user is calculated. There are different methods for DOA estimation.
