Abstract
Smart antenna could adaptively track the users' signal while nulling the interference.It could be used to improve the communication capacity and frequency reusing.Smart antenna plays an important role in the 3G mobile communication system.As the key technique of the smart antenna,the adaptive beamforming algorithm has enjoyed widespread popularity.In this paper,the development and the basic conception for the smart antenna were introduced.The emphasis was laid on the adaptive beamforming algorithm for smart antenna.The algorithm was classified into three sorts according to their computational fields.Several representative algorithms of each sort were also provided.Finally,a kind of important algorithm named blind beamforming algorithm was discussed.
