Abstract: There are some problems affecting mobile communication quality because of reciprocity between mass users. Along with the hotspots and difficulties of communication technology, we discuss working principle and main function of smart antenna. The smart antenna can auto-adaptively track the subscriber signal. The beam forming algorithms of the smart antemna are discussed. According to the algorithm and the way of o signal processing the problem of classification is resolved. And the algorithm is optimized. The optimized algorithm has three merits, such as skipping out nothing. So the algorithm has the solution of the problem and the important status in the third generation mobile communication system.

Key words: smart antenna, beam-forming algorithm, third generation(3G), code division multiple access(CDMA)
