This paper presents analysis of simulation results for Direction of arrival estimation for smart antenna system using non Eigen value decomposition based algorithm. Direction Of Arrival (DOA) estimation in smart antenna for identifying the directions of the desired signals and the null steering beamformer to adapts the antenna pattern to steer the main beam towards the desired user and nullify all other interference. Once DOA estimation is over using beamforming algorithm beam form in desired direction using any one beamforming algorithm. This system can be used to reduce multipath and co-channel interference. This paper simulation results showing performance of power spectra for DOA estimation using PM appear for smart antenna system.
