Advances in Smart Antenna Systems for Wireless Communication

Wireless communication is one of the fastest growing fields of communication industry. Cellular phones have shown the drastic exponential growth from the last decade and this growth has reached about one billion mobile phone users worldwide. Certainly, mobile phones have become one of the most importants components of daily life and a critical business tool in all countries. Huge gap between a vision for future wireless communication systems and the current system’s performance represents that massive research work has to be carried out to make future communication system vision a reality. In this paper, all most all the types of beamforming and direction of arrival schemes for wireless communications have been presented. This paper also presents the comprehensive study of smart antenna systems, its advancement in recent years and futuristic scope.
