Adaptive smart antennas in 3G networks and beyond

The demand for mobile communication systems has dramatically increased in recent years. New concepts and methods, which can optimally exploit the limited resources, are necessary which required the need for new Technologies to satisfy that demand. Smart antenna system is one of those, which combats the co-channel interference and maximizes the user capacity of mobile communication system By shaping and locating the beam of the antenna on the mobile or the target thus decreasing interference to other users. It is now recognized by its higher user capacity in 4G wireless networks by efficiently reducing multipath fading. This paper presents a tool for the modelling, analysis and simulation of Smart Antenna System direction-of-arrival (DOA) estimation and adaptive beamforming needed in the design of smart antenna arrays for wireless mobile communications. The performance of smart antenna system had been studied for some linear and planar array antennas with different numbers of elements. Starting by transmitting the signal through smart antenna system, receiving it and calculating its BER under some 3G Network parameters environment.
