Enhance the Performance of AOA Estimation us using Music Algorithm by Changing Parameters of the Antenna

Abstract
Smart antenna technology in mobile communication is one of the most promising techniques enhance the capacity of communication networks. One of the problematic issues in smart antenna is the detection of arrival signal in different angles in multipath Rayleigh fading channel. In this paper a new smart antenna signal processing method for estimating the signal angle of arrival (AOA) is proposed, by using MUSIC method for wireless communications. MUSIC is a well-known high resolution Eigen structure method. In this paper by changing various parameters of antenna we can enhance the performance of estimation process. The simulation is conducted under different random signal arrivals and space between array elements. The achieved results show that the proposed method determined exact angle of arrival estimation.
