Abstract

The adoption of smart antenna system in future wireless systems is expected to have a significant impact on the efficient use of the spectrum, the minimization of the cost of establishing new wireless networks, the optimization of service quality and the realization of transparent operation across multi technology wireless networks. They are not like conventional antennas that broadcast energy over the entire cell but they are antenna arrays that confine the broadcast energy to a narrow beam. Smart antenna system combines multiple antenna elements with a signal processing capability to automatically optimize its radiation. The main purpose of this paper is to provide an overview of research in the area of smart antennas and to describe how they can be used in wireless systems.Keywords: Smart antenna, wireless network, digital signal processingCite this ArticleVS Joshi, AM Kothari.
