This paper presents wireless communication and it's simulation results using adaptive smart antenna system based on direction of arrival estimation and null steering. Direction Of Arrival (DOA) estimation is based on the PM algorithm for identifying the directions of the desired signals and the null steering beamformer adaptively adapts the antenna pattern to steer the main beam towards the desired user and nullify all other interference. This system can be used to reduce multipath, co-channel interference and provide value added services.
