Smart Antenna Design Based on MUSIC and LMS Algorithms

Liu Yi,Li Li,Zhang Jing(College of Mathematics and Sciences,Shanghai Normal University,Shanghai 200234,China)  
A smart antenna system based on estimated direction of arrival(DOA)and adaptive beamforming achieves DOA and identifies the directions of the received signals around the array antenna by the MUSIC algorithm,controls the direction of the main beam by the LMS algorithm and thus tracks the desired source signal,and at the same time generates deep nulls in the direction of interfering signals.Matlab simulation results show that the MUSIC algorithm can identify the direction of the signal received at the antenna and that the LMS can suppress the interference signal.
