Open publisher page 1 citations

Abstract

The basic question of DOA estimation is to confirm the special positions of the interested signal in a certain area.(Namely,the azimuth angle of each signal arriving reference array antennas,DOA for short).Acquiring DOA information is one of the key techniques in smart antennas technology.This paper focuses on the research of delay-addition algorithm,capon algorithm,conventional MUSIC algorithm and modified MUSIC algorithm.The paper compares the performances of various DOA algorithms through the simulation.
