Smart antenna is one of the recent technologies of communication. If users have accurate Direction Of Arrival (DOA) and Beam forming algorithm, then smart antenna gives good quality of signals in wireless communication. There are various methods to find DOA. The MVDR (Minimum Variance Distortion less Response) method finds the DOA of signal, but due to spectral leakage locations are shown by spurious peaks. The classical beam former method also produces some spurious peaks. MUSIC (MUltiple SIgnal Classification) algorithm gives higher accuracy and resolution than the other methods.
