Abstract

A smart antenna system attracts a lot of attention now a days and believed to be more in the future. The smart antennas when used in communication system, enhances the system capacity, efficiency and bandwidth. From the past decade huge amount of research has been carried out in array signal processing to improve the communications systems. In this paper, most popular beamforming methods used in array signal processing are discussed in terms of its benefits and the reason for its popularity. Furthermore, various fixed weight beamforming and adaptive beamforming techniques are also discussed in this paper. A simulation of beamforming in a particular direction of interest with nulls in interfering o o directions is done using MATLAB simulation software. Array factor for the range between -90^o ≤ θ ≤ 90^o are plotted The purpose of this article is to give an overview of the technology and used beamforming techniques.
